I'm getting this error when trying to use the MS IE Treeview controls. Has
anyone seen it before? I can post the code if needed but Quote doesn't
appear anywhere near my xml or xsl that powers the treeview control. I'm
using a page thats got the asp:xml control on it to transform the xml to the
treeview schema.

Server Error in '/' Application.

This is caused by data in your treeview containing an unescaped "
character. Like value="He was "crazy" "

Try using the html escape character " instead of ". (Run a replace
if needed)

Thanks,

Here's my source code:

            </form>
        </font>
    </body>
</HTML>

</SOURCE_CODE>

The odd thing that I'm finding is that if i go to the xml page directly
(xslvoodo.aspx) i can see the xml it renders nicely and appears to be
correct. I can then save that off in a separate file and pass that filename
to the ie treeview control and poof it works. But it won't work if i pull
it from the aspx page. I've got the content type and character set on the
aspx page. Any ideas?

here's the xml

<?xml version="1.0" encoding="utf-8" ?>
<TREENODES>
<TREENODE Text="Knowledgebase"
NavigateUrl="/protected/nav/router.aspx?ItemId=1015">
