Click on a button in a table when button name changes periodically

I'm using Python and Selenium to click through a site to select and reserve a room. The site presents a table of rooms available. I want to find a specific room and click on the button in the table that is associated with that room....but the button name changes depending on where the room is located in the table. Where it is located depends, in part, on what other rooms are available at the time I run through the website.
In this example, I want to reserve 'Room 34".
The table appears to be identified by:
<table id="MainContent_tblPage"....>
The row or section of the table that includes "Room 34" is identified by the following (which changes depending on where Room 34 appears in the table...which depends on how many other rooms are available):
<tr id=MainContent_rptrPropertyList_trContent_1" >
The button I want to click in this example is:
name="_ctl0:MainContent:rptrPropertyList:_ctl2:rptPropertyRooms:
_ctl0:btnSelect"
(...but the button name changes depending on which other rooms appear in the table...)
My question: How do I find and click the correct button in a table if the button name changes dynamically depending on table content/rows...but the button is always in a row with the text I want to find?
HTML of the section I'm looking at (...sorry, I'm not sure how to make it more readable without the possibility of changes things that might be important for answering my question):
<table id="tblPropertyList" cellpading="0" cellspacing="0" align="center" border="0" width="100%">

EDIT: I'm currently working past this issue by hard-coding the button I'm clicking. I use Selenium to navigate to the webpage that creates a table of the rooms available and then I click on the appropriate button as it stands today. But the name of the button will change in the future:
room34 = browser.find_element_by_name('_ctl0:MainContent:rptrPropertyList:_ctl31:rptPropertyRooms:_ctl0:btnSelect')
room34.click()
EDIT 2: I've played the suggestion from #Grasshopper. His code didn't work for me, but I made some changes that I thought made progress....I was mistaken. I'm removing the rest of Edit 2 so as not to confuse the issue.

To click on the button with name as _ctl0:MainContent:rptrPropertyList:_ctl2:rptPropertyRooms:_ctl0:btnSelect with respect to the element with text as Room 34 you can use either of the following line of code :
Using following :
driver.find_element_by_xpath("//div[#class='room_grid_image']/a[contains(#title,'Room 34')]//following::input[1]").click()
Using following-sibling :
driver.find_element_by_xpath("//div[#class='room_grid_image']/a[contains(#title,'Room 34')]//following-sibling::input[1]").click()

Try this xpath - "//div[normalize-space(.)='Room 34']/ancestor::tbody/tr/td//input[#type='submit']"
The 'Room 34' can be substituted by a python variable. normalize-space is required as the text has a lot of white space.

append Buttons and Callback funcktion to copy information from <tr>...</tr>

I have the following HTML report generated by a software (Navisworks):
<tr class="contentRow">

I would like to do the following:
add a Button after each <a></a> tag
append a function that will collect the ID of the
<td class="item1Content">
<i>Element ID</i>:

and the ID of the
<td class="item2Content"><i>Element ID</i>:
576096
</td>
and copies it to the clipboard
Could someone give me a starting point where to look? I am pretty new to jQuery.

Try the following code:
var rows = $('#testTable > tbody > tr');
$.each(rows, function(index, value){
$(`<input type="button" value="Get Info"/ onclick="getInfo(this)">`).appendTo($(this).find('td:first-child'))
});
function getInfo(that){
var id1 = $(that).parent().parent().find('.item1Content')[0].innerText;
var id2 = $(that).parent().parent().find('.item2Content')[0].innerText;
console.log(id1);
console.log(id2);
}

Having a table,an iframe,and a table displayed side by side

I'm trying to display a table, an iframe, and a table side by side. There are no breaks or anything in between. I'd like all three centered preferably.
This makes no sense. There is plenty of room for them all to be displayed on the same "line" as my screen display is large enough.
Please help.
Code shown below:
<center>
<table border="0">
<tr id="hidethis" style="display:none;">
<td><iframe src="menu.html"height=450 width=400 frameborder=0 name = "list" style =""></></iframe></td>
</tr>
<tr id="hidethisalso" style="display:none;">
<td>Enter code for song to play</td>
</tr>
</table>
<iframe height=450 width=450 frameborder=0 name = "cake" style =""></></iframe>
<table border="0">
<tr id="hidethistoo" style="display:none;">
<td><iframe src="menu.html"height=450 width=400 frameborder=0 name = "list" style =""></></iframe></td>
</tr>
<tr id="hidethisaswell" style="display:none;">
<td>Enter code for song to delete</td>
</tr>
</table>
</center>

Wrap the table in <div style="inline-block">...</div>
this will make the table behave for you
<center>
<!-- wrap the table in an inline-block to make it behave -->
<div style="display:inline-block">
<table border="0">
<tr id="hidethis" style="display:;">
<td><iframe src="menu.html"height=450 width=400 frameborder=0 name = "list" style =""></></iframe></td>
</tr>
<tr id="hidethisalso" style="display:none;">
<td>Enter code for song to play</td>
</tr>
</table>
</div>
<iframe height=450 width=450 frameborder=0 name = "cake" style =""></></iframe>
<!-- wrap the table in an inline-block to make it behave -->
<div style="display:inline-block">
<table border="0">
<tr id="hidethistoo" style="display:;">
<td><iframe src="menu.html"height=450 width=400 frameborder=0 name = "list" style =""></></iframe></td>
</tr>
<tr id="hidethisaswell" style="display:none;">

remove table tr that have specific content

I have the following form inside SharePoint 2013 web application :-
I need to remove all the Table <tr> except the ones that start with "name" & "title". so can anyone adivce how i can achieve this ? . here is part of the markup for the above image (it show two Tr on that have Content Type (should be removed), while the other contain Name ):-
<table id="formTbl" class="ms-formtable" width="100%" cellspacing="0" cellpadding="0" border="0" style="margin-top: 8px;">
<tbody>
<tr>
<td class="ms-formlabel" valign="top" nowrap="true">
<h3 class="ms-standardheader">Content Type</h3>
</td>
<td class="ms-formbody" valign="top">
</tr>
<tr>
<td class="ms-formlabel" width="113px" valign="top" nowrap="true">
<h3 class="ms-standardheader">
<nobr>
Name
<span class="ms-accentText" title="This is a required field."> *</span>
</nobr>
</h3>
</td>
<td class="ms-formbody" width="350px" valign="top">
</tr>
<tr>
<tr>
<td class="ms-formlabel" width="113px" valign="top" nowrap="true">
<td class="ms-formbody" width="350px" valign="top">

Now i have jquery version 1.7 loaded inside the web application, but i prefer to achieved using pure javaScript.
Thanks

When in doubt, filter is your friend:
JSFiddle: http://jsfiddle.net/TrueBlueAussie/jjzx6mge/4/
$('#formTbl tr').filter(function () {
return !$(".ms-standardheader", this).text().match(/Name|Title/i);
}).remove();
The result returned of a function passed to filter is a boolean value telling which items to retain (truthy), or which to exclude (falsey).
This one targets only rows that have the requested text in the ms-standardheader classed element.
It also only targets a specific inner table to avoid the case of deep searching from the top level table and wiping out entire tables within it.
While you can do this with plain old JS, significantly more code is required.As you already have a version of jQuery installed, it makes sense to use it.

This would work:
$(function() {
$('#formTbl tr').each(function() {
var frstVal = $(this).find('td').eq(0).text();
if (!frstVal.match(/name|title/i)) {
$(this).remove()
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<table id="formTbl" class="ms-formtable" width="100%" cellspacing="0" cellpadding="0" border="0" style="margin-top: 8px;">
<tbody>
<tr>
<td class="ms-formlabel" valign="top" nowrap="true">
<h3 class="ms-standardheader">Content Type</h3>
</td>
<td class="ms-formbody" valign="top">
</tr>
<tr>
<td class="ms-formlabel" width="113px" valign="top" nowrap="true">
<h3 class="ms-standardheader">
<nobr>
Title
<span class="ms-accentText" title="This is a required field."> *</span>
</nobr>
</h3>
</td>
<td class="ms-formbody" width="350px" valign="top">
</tr>
<tr>
<td class="ms-formlabel" width="113px" valign="top" nowrap="true">
<h3 class="ms-standardheader">
<nobr>
Name
<span class="ms-accentText" title="This is a required field."> *</span>
</nobr>
</h3>
</td>
<td class="ms-formbody" width="350px" valign="top">
</tr>
<tr>
<tr>
<td class="ms-formlabel" width="113px" valign="top" nowrap="true">
<td class="ms-formbody" width="350px" valign="top">
</tr>

This will remove every tr that has a .ms-standardheader element that contains the text Name or Title
$('#formTbl tr').each(function() {
var that = $(this);
var label = that.find('.ms-standardheader').text();
if (label.indexOf('Name') != -1 || label.indexOf('Title') != -1) {
that.remove();
}
});

And here I am, doing this the good ol' plain JS way, since you've asked for it :)
http://jsfiddle.net/m53esfpo/3/
Edit: Updated code and fiddle (thanks #TrueBlueAussie)
Removes every tr except the ones that start with name or title.
var t = document.getElementById('formTbl');
for (var i = 0; i < t.getElementsByTagName("tr").length; i++) {
var s = t.getElementsByTagName("tr")[i].getElementsByClassName('ms-formlabel');
if (s.length > 0) {
if (s[0].innerText.indexOf('Name') < 0 && s[0].innerText.indexOf('Title') < 0) {
t.getElementsByTagName("tr")[i].parentNode.removeChild(t.getElementsByTagName("tr")[i]);
}
}
}

You can do it with this:
$("#formTbl tr td h3").not("h3:contains('Name'):contains('Title')").closest('tr').remove();

Remove all images from a table and insert it before

I have the following HTML table:
<div class="someClass" id="someID">
<!-- Move all images inside the td's here -->
<table cellspacing="0" cellpadding="0" style="width:100%;border-collapse:collapse;" id="mainTable">
<tbody>
<tr>
<td align="center">
<img width="127" height="191" border="0" src="Images/9.jpg" class="bvz_beeldthumb">
</td>
<td align="center">
<img width="127" height="191" border="0" src="Images/10.jpg" class="bvz_beeldthumb">
</td>
</tr>
<tr>
<td align="center">
<img width="127" height="191" border="0" src="Images/11.jpg" class="bvz_beeldthumb">
</td>
<td align="center">
<img width="127" height="191" border="0" src="Images/12.jpg" class="bvz_beeldthumb">
</td>
</tr>
....
</tbody>
</table>
What I want is go trough each td and remove the image and insert it before the table. And than remove the entire table.
What is the best way to do this?
Thanks.

You can use jQuery and use each() to iterate through all of the td elements and move all of the images within td before the table.
$('td').each(function(){
$('img').insertBefore('table');
$('table').hide();
});
SEE DEMO

I got this working:
WORKING FIDDLE
$(document).ready(function(){
$('.bvz_beeldthumb').each(function(){
$('.someClass').append(this);
});
$('#mainTable').remove();
});
Document ready means that when the document is ready the code will be fired.
It finds all images with class bvz_beeldthumb on the page and moves it to the div someClass. After that it removes the table.

Try This
$("#mainTable td").each(function() {
var Img=$(this).find("img");
$("#someID").prepend(Img);//here element 'id' in which you want to put these images.
$(this).find("img").html('');
});
I hope this helps you!!

You can try something like
$('#mainTable img').insertBefore('#mainTable')
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<table cellspacing="0" cellpadding="0" style="width:100%;border-collapse:collapse;" id="mainTable">
