[RESOLVED] Reading XML Doc in Javascript

bpat1434

Hey all... trying to get an xml document like the following parsed, so that the inner element will be ready by javascript:

<?xml version="1.0" encodig="iso-8859-1"?>

<page title="home">
</page>

<page title="about">
</page>

Basically, one XML file will hold all the information for the site. And the site (being AJAX-ish) will use Javascript to read from the xml file. I'm getting it via an XML request response. So here's the real question:
What is the best way to get the proper node (page) based upon the user selection?

Would it be better to wrap the initial stuff in a separate tag, then find the proper child node? Something like:

<pages>
  <page title="home">
  </page>

  <page title="about">
  </page>
</pages>

Thanks for any help you can offer.

You'll need a root node (like <pages>) otherwise the XML would not be well-formed; what the Javascript DOM-traversal methods will do in that case I don't know.

Given that, you could getElementsByName() to pick out the <page> elements, then look for ones with the appropriate title attribute .... It's possible to specify which attribute is the "id" in the DTD, but I don't know how to get Javascript to make use of that.

So would it be better to use PHP to take the XML document and have it spit out just the node that I want? Seems like that may be the better option...

Er, yeah 🙂 But it's not getElementByTagId() Oh the joys of a consistent naming scheme...

If you're only interested in one or a very few nodes per page view I reckon that would be the way to go. There' a tradeoff: send everything up front whether it's needed or not and save communication time later, or send only what's necessary and ask for more later as it's needed.
