You are using value-of, which does what it says: it gets you the "value" 
of the selected nodes (i.e., the "value", that is a string and not a 
node set and cannot be processed further). Use, in XSLT 2.0, copy-of, 
sequence, apply-templates or @select, or, in XSLT 1.0 just use @select.

you probably tried something else than you state above: 
document(file:///bla) is a syntax error and cannot compile. Try 
document('file:///bla').

again, this cannot compile. If you did use quotes in your original and 
indeed got this warning: your URL is malformed. It should be either 
file:///c:/a/b/c/index.hmtl (where the first // means: localhost) or it 
should be file:/c:/a/b/c/index.html, where the absence of the first // 
means, again, localhost. If you do not want localhost but another 
server, place that address between // and /, like this: 
file://otherhost/c$/some/file/here.html.

By now I assume you just mistyped the function in your mail and did the 
right thing in your real-world stylesheet. Since you have a network 
address error here, you should try your PHP directly to try to fetch the 
document. Probably you are behind a firewall, a proxy or anything and 
your PHP just cannot access the external url.

In general, use "file:///c:/my/path/on/c-drive/index.html" for files, 
and use "http://www.google.com/index.html"; (won't work, google does not 
serve valid xhtml, but the syntax should work and it should not give you 
the error you mention).

HTH,
