Node.Js data upload to MongoDB - Text file to array to object? - javascript

I'm trying to take a txt file that looks like.
HCI Version: 4.0 (0x6)
HCI Revision: 0x23A1
LMP Version: 4.0 (0x6)
LMP Subversion: 0x4176
I'm trying to put said file into Mongodb in JSON format via node. The more i dig in the more i'm losing my mind. I was just introduced to node streams. Any thoughts would go a long way and thanks in advance.

You can either use regex or use split on the colon for each of the rows.
For the first one your regular expression could look something like:
/HCI Version:.+?(?=\))+\)/g

Open XML file in AppleScript with JavaScript syntax

I am writing my first bigger AppleScript and as I am usually developing TypeScript, I decided to use the JavaScript version of AppleScript. I need to read and parse an XML file.
Apple has an Example for that on their documentation, however the documentation only has an example in the AppleScript syntax, not in the JavaScript syntax:
https://developer.apple.com/library/archive/documentation/LanguagesUtilities/Conceptual/MacAutomationScriptingGuide/WorkwithXML.html#//apple_ref/doc/uid/TP40016239-CH67-SW1
How do I actually do the given example in JavaScript?
I can read the file as a String, but that does not help me as I need to traverse the XML-tree.
In the end I used webpack and an npm-package for parsing XML files to JSON: https://www.npmjs.com/package/fast-xml-parser
my code example is here:

Any javascript method like php "glob" to get filenames or directories that match the specified pattern?

I am a newbie of javascript and I would like to create very simple web apps
I order to get filenames or directories that match the specified pattern.
I can using glob in php
glob("*.txt")
How about javascript?? Thank you very much
Either Array.every() or you can do a custom Array.map() with conditioners. You do need to supply a list of names though as it's tough doing with vanilla JS because of security reasons..

Open and save xml file from jmeter command line

I am trying to manipulate jmeter test plan in a web based tool. The problem is, it converts many characters to implicitly. For example " converts to ", 
 converts to newline.
I observed that, if i open that modified file from jmeter ui and save it without doing anything, all the characters are converted back to original. For example " converts to ".
So is it possible to do this automatically using jquery/javascript. I am using angularjs with node.js for my application. I would prefer to do this open-save-close operation in background. Please suggest , how can i achieve this. is there any jmeter-plugin available which i can run from javascript/jquery ?
Many thanks in advance
You need to escape the following characters in XML, otherwise it will result into invalid markup.
"
'
<
>
&
Given you use NodeJS you can use xml-escape function to do the trick for you.
JMeter provides __escapeXML() function out of the box just in case you're looking for Java-based implementation, see Apache JMeter Functions - An Introduction article to get familiarized with JMeter Functions concept.
What jmeter is doing with XML is correct and is done by the library XStream.
JMeter manipulate Java Objects and serializes them using XStream.
I am not sure what you are trying to do, but I don't think it is correct in terms of maintainability, indeed JMeter doesn't provide any contract on XML (XSD or DTD). Test plans should be manipulated through Java.
As far as I know, you cannot manipulate it through javascript, but you can potentially use this DSL to manipulate/generate test plans:

jQuery or Javascript: Convert from ISO-8859-1 to utf8

one API that I have to use returns the text using ISO-88951-1, so the words with spanish accents like "obtendrá" are wrong codified when I show them to the user (the valid output would be "obtendrá").
How can I transform the text to UTF-8? I need a function in javascript or jQuery to perfom this conversion.
Thanks
There are at least a couple of modules on npm that let you do encoding conversions: iconv (requires compilation) and iconv-lite (doesn't require compilation).
Finally I achieve what I need using:
$("<div>").html(theTextinHex).text();
Thanks anyway!
