XSL: Transform links and sources to an absolute URL

[Plew]

Hello

this is my first post here, so i hope somebody can help me?
I have an XML file like this, with relative and absolute URL`s


<images>
<img src="Loading Image..." alt="" width="800"
height="600" />
<img src="/test/bar.jpg" alt="" width="800" height="600" />
</images>
<links>
<a href="www.foo.de">...hi there</a>
<a href="/test/test.html">bar</a>
</links>

..and know I need a way to append the absolute URL to the relative
path`s to prevent errors, when i`m generating HTML on my server with an
xslt.
Whats the best way? Pass a parameter with the URL to the XSLT? How can I
dynamically add this to an src or href?

I`m using Saxon with XSLT 2.0.


greetings Stefan

Which absolute URL? The ones from the image elements that are
absolute, or the absolute URI of the XML file itself?

Yes, if that is different than the absolute URI of the file itself.

For any given node you in the source tree can get the absolute URI of
the source base document in XSLT 2 using:

document-uri( root( $node ) )

resolve-uri( $relative-uri, $base-uri )

I hope this helps.

In addition to Ken's advice note that

<a href="www.foo.de">

is a relative URL to a file www.foo.de in the current directory, it's
probably a user error in the source, and should be http://www.foo.de
the functions that Ken mentioned won't fix that error, it's probably
best just to fix the source, but if you want the stylesheet to
dynamically fix it then you'll need some heuristics with replace()
perhaps replace(@uri,'^www\.','http://www.') or ....
