Hi For me it doesn't look like a bug. XSLT for normal does not produce error messages.
Instead of: # xsltproc --param value "ival" test.xslt test.xml Use # xsltproc --param value "'ival'" test.xslt test.xml or # xsltproc --stirngparam value "ival" test.xslt test.xml Bernhard Stefan Behnel wrote: > Hi, > > any comments on this one?
