I need to put some embedded xml within a web page. It has to be in the
webpage.

Is their a way I could use this xml as a datasource for an extended Ajax
cascading dropdown and not have postbacks (preferred) or just for some
cascading DDLs.

dropdownlist one: CarManufactures

dropdownlist two: Models

I've used ajax cascading dropdowns and xml. However,I have no clue on how
to grab the xml from withing the webpage, filter it, and use it as a
datasource for the dropdownlists.

Embedding XML in an XHTML document is possible if parsed by an XML
parser. Browsers like Mozilla, Opera, Safari support that where you
serve your XHTML as application/xml and embed elements in a different
namespace than the XHTML namespace.

IE knows so called XML data islands where the HTML parser supports an
element named xml to insert XML inline or referenced from a document. See

If you want cross-browser stuff with a HTML document served as text/html
then in my view you can't embed the XML in the HTML document, rather you
use separate XML document and load that using XMLHttpRequest
(respectively new ActiveXObject('Msxm2.XMLHTTP.3.0') in IE 6).

Hello Chuck,

I'm not sure I have understood the issue correctly.
It seems like you want to grab the embedded xml content from the web page.
Your end user is using Linux or Mac Computers. Thus, it is not possible for
you to use IE. Am I missing something?

If this is the case, in my opinion, you could use System.Web.HttpRequest to
grab the whole web page(HTML) and then exact the XML content(which you
need) by System.Text.RegularExpressions.

I could found some example on this method if you are interested in it.
Please let me know if this is what you need. Thanks.

Hope this helps
Sincerely,
Wen Yuan
