Trouble retrieving inner text from XML node using JavaScript

Question

I'm reading an XML document using JavaScript & jQuery, and need to extract some text from inside a node to save into an array. The structure of the XML is as such:

<C>
  <I>
    <TEXTFORMAT>
      <P>
        <FONT>Here's the text I want</FONT>
      </P>
    </TEXTFORMAT>
  </I>
</C>

Everything I've tried so far returns nothing so I must be incorrectly referencing the contents of the FONT tag.

What XML path should I be using?

That does work, however it retrieves the content of every FONT tag in the XML, I need it to only retrieve the content of the node it's currently looking at. What should I change? — Jack Roscoe

<FONT>? ouch. What have you tried? sounds like $("font") would work fine in this situation. — marcgg

What does "the content of the node it's currently looking at" mean? What is it and why is it staring at your nodes? — user113716

@JackRoscoe - if you are already working on pieces of the XML document, you can use jQuery to work on those pieces too, rather than the entire document. So instead of $(myEntireXmlDoc).find(...), do $(theContentIAmLookingAt).find(...). Also, if you are already working on a raw XML object, you should be able to drill down to the text like this: theXmlIAmLookingAt.getElementsByTagName('font')[0].firstChild.nodeValue. — Andrew

This will give you an array of the content of the FONT nodes.

var array = $(xml).find('FONT').map(function() {
    return $(this).text();
}).get();

function parseXml(xml)
{
    //find every FONT element and store its value
    $(xml).find("FONT").each(function()
    {
        // put this.text() into the array
    });

}
