Your input is not a well-formed XML document. You've probably made the
mistake of having non-whitespace text before the root element. Fix your
input.

hi joe, thx. the problem lies on less than and greater than signs in
this string: "<a>testing </a>"; I tried another approach by calling a
using a function in xsl that return this string. but the output of xsl
contains but < and > which the broswer doesn't understand. I
need these signs after calling the getting the string from the
function. Any idea?
thx

If you're outputting HTML for use in a browser, you should probably
consider setting the output mode to HTML rather than XML (see the
documentation for the xsl:output directive). That will switch to a
serializer which is more likely to be compatable with the typical browser.

But I think a browser which doesn't understand < and > should
probably be consdered broken...?

This way, the content of this section does not have to use a prefix for the shared namespace, thus making the document smaller and easier to read.
