How to get the attribute Value of an xml tag created with namespace?

<root xmlns='http://www.w3.org/2005/Atom' xmlns:element='http://search.yahoo.com/mrss/'>
<element:group>
<element:content url='https://myrequiredurl.com' otherattr='360' otherattr='640' otherattr='somthng' medium='smtng'/>
<element:content url='https://myrequiredurl.com' otherattr='720' otherattr='1280' otherattr='smtng' medium='smtng'/>
<element:content url='https://myrequiredurl.com' otherattr='1080' otherattr='1920' otherattr='smtng' medium='smtng'/>
</element:group>
</root>
Above is my xml doc i need to get the 'url' attribute from first '<element:content/>' tag i tried the ways mentioned in w3schools.com but i had
no luck some help is much appreciated i need to access it using javascript sorry for bad question framing

You can simply achieve this using dom manupulation.
HTML:
<p id="show"></p>
Javascript:
var urlList = [];
var txt = "<root xmlns='http://www.w3.org/2005/Atom' xmlns:element='http://search.yahoo.com/mrss/'>" +
"<element:group>" +
"<element:content url='https://1myrequiredurl.com' otherattr='somthng' medium='smtng'> </element:content>" +
"<element:content url='https://2myrequiredurl.com' otherattr='smtng' medium='smtng'> </element:content>" +
"<element:content url='https://3myrequiredurl.com' otherattr='smtng' medium='smtng'> </element:content>" +
"</element:group>" +
"</root>";
if (window.DOMParser) {
parser = new DOMParser();
xmlDoc = parser.parseFromString(txt, "text/xml");
}
else // For Internet Explorer
{
xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async = false;
xmlDoc.loadXML(txt);
}
var group = xmlDoc.getElementsByTagName("root")[0].childNodes[0].childNodes;
for (var content in group) {
if (!isNaN(content)) {
var url = group[content].getAttribute("url")
urlList.push(url);
}
}
document.getElementById("show").innerHTML = urlList.join("</br>");
P.S: "You cannot add multiple attributes with the same name".

cannot get xmlDoc to load any value. Keep getting null values

I have an xml file that I retreive via terminal emulation. I want to parse the results into a textarea in html. I am able to view the file in the textarea in xml format but have been unable to parse it into lines of the inner text.
Here is the javascript/jquery:
var x = ""
var y = ""
var Command="";
var cmd=""
$(document).ready(function() {
alert('jquery working');
$('#tester').click(function() {
$("#disptext").val("");
var APOresp = new ActiveXObject("DAT32COM.TERMINALEMULATION");
var Command = "<FORMAT>>*IA</FORMAT>";
APOresp.MakeEntry(Command);
//APOresp.GetMore(true,false);
var x = APOresp.ResponseXML;
APOresp.Close();
xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async = "false";
xmlDoc.loadXML(x);
$(x).find('RESPONSE').each(function() { //these lines do not work. I get null xmlDoc reference
$("#disptext").val($(this).text() + "<br />");
});
//$("#disptext").val(xmlDoc.xml); //disptext is the textarea
});
Here is what a portion of the text file looks like:
?xml version="1.0"?>
<!--This is a host terminal response-->
<RESPONSE xmlns="x-schema:C:\fp\swdir\Content\emulation-schema.xml">
<LINE INDEX="1"><![CDATA[SIGN IN ]]><CARRIAGE_RETURN/></LINE>
<LINE INDEX="2"><SOM/></LINE>
</RESPONSE>
Most files are much longer.
I want to get the text for each "LINE: tag and loop it into the textarea. It does put in the whole xml file in xml format if I use the last commented out line in the javascript file. For some unknown reason, I am unable to use the xmlDoc. I keep getting errors that the xmlDoc has null values. I have been trying to fix this for a number of days without success. Any help would be greatly appreciated.

Read lines from a file and import as youtube embed to my site

I want to know how to read text file and get the information to a javascript code.
What I mean is,
If I have text file contained with youtube Video-ID and Title
ID:youtubeVideoID1 "Title1"
ID:youtubeVideoID2 "Title2"
ID:youtubeVideoID3 "Title3"
ID:youtubeVideoID4 "Title4"
for example:
ID:gsjtg7m1MMM "X-Man Trailer!"
I want that my web (Index.html) will read the text-file's lines 1 by 1 ,by order,
and show me on my web embed of youtube videos like this:
<img width="143" alt="(TITLE)" src="http://img.youtube.com/vi/(VIDEO_ID)/hqdefault.jpg" >
It need to read and show only the lines that start with "ID:" and the first word after ID is the VIDEO_ID (so it should be a VAR) and after "space" comes the "TITLE" (and it can be a few words in some language) should be a var also..
so If I have only 5 rows in the text file with ID + TITLE, it will show me on the page, only 5 embed videos...
and if there is more, then more...
and if its javascript, what code I need to write on the web so it will show?
Thank You!
hope someone will help me with that..

This seems relatively simple.
First off we need to read the txt file:
function readTextFile(file)
{
var rawFile = new XMLHttpRequest();
rawFile.open("GET", file, false);
rawFile.onreadystatechange = function ()
{
if(rawFile.readyState === 4)
{
if(rawFile.status === 200 || rawFile.status == 0)
{
var allText = rawFile.responseText;
return allText;
}
}
}
rawFile.send(null);
}
var txt = readTextFile("path/to/txt/file.txt");
Then we need to parse the file, so assuming the file looks like above we could do it like this:
var split_txt = txt.split("ID:");
for(var i=0;i<split_txt.length;i++){
var id = split_txt[i].split(" \"")[0];
var title = split_txt[i].split(" \"")[1].slice(0,-1);
$("body").append("<img width=\"143\" alt=\""+title+"\" src=\"http://img.youtube.com/vi/"+id+"/hqdefault.jpg\" >");
}
You will require jQuery to run it.

print entire xml data and tags in html - javascript [duplicate]

I want to convert an xml element like this:
<asin>​B0013FRNKG​</asin>​
to string in javascript
I used XMLSerializer:
new XMLSerializer().serializeToString(xml);
the string only shows on alert() and in the console. On the page it just says
[object Element][object Element]
I want to get the string.

You haven't told us how you go about displaying that object. XMLSerializer works on DOM nodes, so your object has to be added somewhere, for example:
document.getElementById('SomeDiv').appendChild(xml);
and if you just want the full xml string to be displayed:
var xmlText = new XMLSerializer().serializeToString(xml);
var xmlTextNode = document.createTextNode(xmlText);
var parentDiv = document.getElementById('SomeDiv');
parentDiv.appendChild(xmlTextNode);

<script type='text/javascript'>
function xmlToString(xmlData) {
var xmlString;
//IE
if (window.ActiveXObject){
xmlString = xmlData.xml;
}
// code for Mozilla, Firefox, Opera, etc.
else{
xmlString = (new XMLSerializer()).serializeToString(xmlData);
}
return xmlString;
}
</script>
use this in case of IE for browser compatibility issues.

function getXmlString(xml) {
if (window.ActiveXObject) { return xml.xml; }
return new XMLSerializer().serializeToString(xml);
}
alert(getXmlString(xml));

Did you try enclosing the result like in…
(new XMLSerializer()).serializeToString(xml)
Also, I'd use console instead to see the content better:
console.log((new XMLSerializer()).serializeToString(xml));

If the DOM element <asin>​B0013FRNKG​</asin>​ is stored in the object element, then you can access the value using:
element.textContent

follow this to print,append data from xml data stored as string inside javscript
txt="<papers>"+"<paper>"+
"<author>athor name</author>"+
"<title>title</title>"+
"<path>path</path>"+
"<track>which tack</track>"+
"</paper>"+
"<paper>"+
"<author>athor name</author>"+
"<title>title</title>"+
"<path>path</path>"+
"<track>which tack</track>"+
"</paper>"+
"<paper>"+
"<author>athor name</author>"+
"<title>title</title>"+
"<path>path</path>"+
"<track>which tack</track>"+
"</paper>"+
"<papers>";
if (window.DOMParser)
{
parser=new DOMParser();
xmlDoc=parser.parseFromString(txt,"text/xml");
}
else // Internet Explorer
{
xmlDoc=new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async=false;
xmlDoc.loadXML(txt);
}
x=xmlDoc.getElementsByTagName("paper");
for (var i = 0; i < x.length; i++) {
var athor =x[i].childNodes[0].firstChild.nodeValue;
var title = x[i].childNodes[1].firstChild.nodeValue;
var path = x[i].childNodes[2].firstChild.nodeValue;
var tack =x[i].childNodes[3].firstChild.nodeValue;
//do something with these values...
//each iteration gives one paper details
var xml=document.getElementById("element_id");//<div id="element_id"></div>
var li = document.createElement("br");// create a new <br>
newlink = document.createElement('A'); // creating an <a> element
newlink.innerHTML = athor;// adding <a>athor value here</a>
newlink.setAttribute('href', path);//
newlink.appendChild(li);// athor<br>
document.getElementById("element_id").appendChild(newlink);//finaly it becomes <div id="element_id">athor<br></div>
}

Create XML in JavaScript

Is it possible to create an XML file with some data in JavaScript? I have the data stored in variables.
I've googled around a bit and it doesn't seem like it's talked about much. I thought I could use XMLWriter such as this:
var XML = new XMLWriter();
XML.BeginNode ("testing");
XML.Node("testingOne");
XML.Node("TestingTwo");
XML.Node("TestingThree");
XML.EndNode();
as stated in this tutorial: EHow Tutorial
However, when I execute this code, I get the following error:
ReferenceError: XMLWriter is not defined
How can I solve this error?

Disclaimer: The following answer assumes that you are using the JavaScript environment of a web browser.
JavaScript handles XML with 'XML DOM objects'.
You can obtain such an object in three ways:
1. Creating a new XML DOM object
var xmlDoc = document.implementation.createDocument(null, "books");
The first argument can contain the namespace URI of the document to be created, if the document belongs to one.
Source: https://developer.mozilla.org/en-US/docs/Web/API/DOMImplementation/createDocument
2. Fetching an XML file with XMLHttpRequest
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (xhttp.readyState == 4 && xhttp.status == 200) {
var xmlDoc = xhttp.responseXML; //important to use responseXML here
}
xhttp.open("GET", "books.xml", true);
xhttp.send();
3. Parsing a string containing serialized XML
var xmlString = "<root></root>";
var parser = new DOMParser();
var xmlDoc = parser.parseFromString(xmlString, "text/xml"); //important to use "text/xml"
When you have obtained an XML DOM object, you can use methods to manipulate it like
var node = xmlDoc.createElement("heyHo");
var elements = xmlDoc.getElementsByTagName("root");
elements[0].appendChild(node);
For a full reference, see http://www.w3schools.com/xml/dom_intro.asp
Note:
It is important, that you don't use the methods provided by the document namespace, i. e.
var node = document.createElement("Item");
This will create HTML nodes instead of XML nodes and will result in a node with lower-case tag names. XML tag names are case-sensitive in contrast to HTML tag names.
You can serialize XML DOM objects like this:
var serializer = new XMLSerializer();
var xmlString = serializer.serializeToString(xmlDoc);

Consider that we need to create the following XML document:
<?xml version="1.0"?>
<people>
<person first-name="eric" middle-initial="H" last-name="jung">
<address street="321 south st" city="denver" state="co" country="usa"/>
<address street="123 main st" city="arlington" state="ma" country="usa"/>
</person>
<person first-name="jed" last-name="brown">
<address street="321 north st" city="atlanta" state="ga" country="usa"/>
<address street="123 west st" city="seattle" state="wa" country="usa"/>
<address street="321 south avenue" city="denver" state="co" country="usa"/>
</person>
</people>
we can write the following code to generate the above XML
var doc = document.implementation.createDocument("", "", null);
var peopleElem = doc.createElement("people");
var personElem1 = doc.createElement("person");
personElem1.setAttribute("first-name", "eric");
personElem1.setAttribute("middle-initial", "h");
personElem1.setAttribute("last-name", "jung");
var addressElem1 = doc.createElement("address");
addressElem1.setAttribute("street", "321 south st");
addressElem1.setAttribute("city", "denver");
addressElem1.setAttribute("state", "co");
addressElem1.setAttribute("country", "usa");
personElem1.appendChild(addressElem1);
var addressElem2 = doc.createElement("address");
addressElem2.setAttribute("street", "123 main st");
addressElem2.setAttribute("city", "arlington");
addressElem2.setAttribute("state", "ma");
addressElem2.setAttribute("country", "usa");
personElem1.appendChild(addressElem2);
var personElem2 = doc.createElement("person");
personElem2.setAttribute("first-name", "jed");
personElem2.setAttribute("last-name", "brown");
var addressElem3 = doc.createElement("address");
addressElem3.setAttribute("street", "321 north st");
addressElem3.setAttribute("city", "atlanta");
addressElem3.setAttribute("state", "ga");
addressElem3.setAttribute("country", "usa");
personElem2.appendChild(addressElem3);
var addressElem4 = doc.createElement("address");
addressElem4.setAttribute("street", "123 west st");
addressElem4.setAttribute("city", "seattle");
addressElem4.setAttribute("state", "wa");
addressElem4.setAttribute("country", "usa");
personElem2.appendChild(addressElem4);
var addressElem5 = doc.createElement("address");
addressElem5.setAttribute("street", "321 south avenue");
addressElem5.setAttribute("city", "denver");
addressElem5.setAttribute("state", "co");
addressElem5.setAttribute("country", "usa");
personElem2.appendChild(addressElem5);
peopleElem.appendChild(personElem1);
peopleElem.appendChild(personElem2);
doc.appendChild(peopleElem);
If any text need to be written between a tag we can use innerHTML property to achieve it.
Example
elem = doc.createElement("Gender")
elem.innerHTML = "Male"
parent_elem.appendChild(elem)
For more details please follow the below link. The above example has been explained there in more details.

xml-writer(npm package)
I think this is the good way to create and write xml file easy.
Also it can be used on server side with nodejs.
var XMLWriter = require('xml-writer');
xw = new XMLWriter;
xw.startDocument();
xw.startElement('root');
xw.writeAttribute('foo', 'value');
xw.text('Some content');
xw.endDocument();
console.log(xw.toString());

Simply use
var xmlString = '<?xml version="1.0" ?><root />';
var xml = jQuery.parseXML(xml);
It's jQuery.parseXML, so no need to worry about cross-browser tricks. Use jQuery as like HTML, it's using the native XML engine.

this work for me..
var xml = parser.parseFromString('<?xml version="1.0" encoding="utf-8"?><root></root>', "application/xml");
developer.mozilla.org/en-US/docs/Web/API/DOMParser

Only works in IE
$(function(){
var xml = '<?xml version="1.0"?><foo><bar>bar</bar></foo>';
var xmlDoc=new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async="false";
xmlDoc.loadXML(xml);
alert(xmlDoc.xml);
});
Then push xmlDoc.xml to your java code.

Your code is referencing this library
You can include it, and then your code in question should run as is. If you want to do this without prepending the library & build it with builtin functions only - follow answer from #Seb3736.
In Browser Example
<html>
<head>
<script src="Global.js" language="javascript"></script>
<script src="XMLWriter.js" language="javascript"></script>
<script language="javascript" type="text/javascript">
function genXML(){
var XML = new XMLWriter();
XML.BeginNode ("testing");
XML.Node("testingOne");
XML.Node("TestingTwo");
XML.Node("TestingThree");
XML.EndNode();
//Do something... eg.
console.log(XML.ToString); //Yes ToString() not toString()
}
