I have a elemet in xsl file like this:
<xsl:value-of select="saxon:evaluate(concat('//xf:instance', @ref))"/>
when I generate to html ,there are exception below.
if I comment the "saxon:evaluate", it is OK running but out of my expectation.
JDK: IBM JDK1.4.1.
classpath:jdom.jar, xalan.jar, xercesImpl.jar, xml-apis.jar...
