Hi,
I'm trying to put the links (href attribute of the <a> element) out of my
XSLT files, in a XML file, and read it from the stylesheet. I suppose that I
have to use the document() function to link to the XML file containing the
URLs, but I don't know how to do it. I've tried something like this:

This is XML file containing the URLs (link.xml):

<?xml version="1.0" encoding="utf-8" ?>
<LINKS>
<L1>
/SomePage.aspx
</L1>
</LINKS>

And this is the code from the stylesheet:

<a href="{document('link.xml')/LINKS/L1}" >
Some text for the anchor
</a>

But does not work. I've tried to move the XML file in different folders to
make the things easy... but with no luck.

How this it's supposed to be done?

Thanks for any suggest.
Mario Vazquez

Should work. Make sure that link.xml is stored in the same directory as
your stylesheet. Also you may want to remove whitespace before and after
link text:

<a href="{normalize-space(document('link.xml')/LINKS/L1)}" >

Another idea - in .NET 2.0 when using XslCompiledTransform class
document() function is disabled by default - you should get an exception
though.

Hi Mario,

That should work. Note that in this case link.xml in resolved relative
to the stylesheet location. If you want it to be resolved relative to
the XML file location then use

<a href="{document('link.xml', .)/LINKS/L1}" >
Some text for the anchor
</a>

That is you need to pass a node set as a second argument to the
document funtion and that nodeset system Id will be used to resolve the
relative location specified as the first argument.

Best Regards,
George

You can declare a parameter e.g.
<xsl:param name="dir" />
in your stylesheet and then pass in a value as needed before you run the
transformation. That way you could for instance use Server.MapPath() in
ASP to determine a file path and pass that then in to the XSLT processor.
