Hi Ken,

When you say it doesn't work, in what way does it not work?

I try to transform it with an xsl-sheet that copies its most part into a new document and makes changes on just some few nodes. And that doesn't work because Saxon throws the error reported.

On the "new" document?

I must not change &a to &amp; within the uri because the server won't be able no more to fetch the GET parameter "a" from the uri. It's not my server.

Regardless, I think that is non-conformant behaviour, but I cannot find a reference online to back me up with that statement.

Isn't it really possible to copy the string as CDATA?

No ... CDATA is syntactic sugar for XML documents ... it isn't meaningful at all. It is just a shortcut for not typing out entities.

After copying the content into a new document (what doesn't work yet) I want to use the <url_download> to dynamically generate links with its CDATA.

Ah ... then you don't have a problem on the way in to the second process, only on the way out to your server.

On the way in to your second process you have to have "&amp;" because the second process is XSLT ... hence the message from Saxon (I hadn't realized you had two processes).

One solution to th '&a' problem would be using the function fn:encode-for-uri (XSLT 2.0) which will transform back the &amp;a to &a. Unfortunately it is not possible because the libxst-processor that is included in PHP and that I must use for 'XSLT on the fly' only supports XSLT 1.0. That's why I must not change &a to &amp;

Then I think you are stuck. What experiments have you run with the server? Have you tried hand-typing &amp; in the URL at the server to see how it complains?

Sorry I have no guidance to get around what I believe is non-conformant behaviour.
