Getting node data from infopath formatted XML

I need to get data from known nodes in an infopath xml. I have the following code Facility returns nothing when I am expecting '140x. Once I have the key to this I will be able to for each my nodes with siblings like my:CompletedByRpt. :( It must work in IE10+ #FeelMyPain

var xmlDoc = $.parseXML(xml); // In debugger I have the xml here. 
var $xml = $(xmlDoc);

Facility = $xml.find('my:cover').find('my:Facility').text();
$("#Facility").append('Facility =' + Facility );

Using this xml source that I do not control: (I made it much smaller and scrubbed a bit)

My thanks in advance for your patience and help.

Solution

Your issue is that the colon (:) is a special character in the jQuery selector. It is used to denote that the following sequence of characters is a pseudo selector, eg. :first or :eq().

To prevent this behaviour you need to escape the : by preceding it with \\, like this:

Facility = $xml.find('my\\:cover').find('my\\:Facility').text();
$("#Facility").append('Facility =' + Facility );
