Description Pavol Rusnak 2007-05-30 09:27:51 UTC 
One of our reporters encountered a strange behavior in XSLT processor when trying to compile Lessons for Lizards. I reduced the files to minimal size and created simple testcase (attached).

File lessons4lizards.xml contains:

<bookinfo>
   <pubdate><?dbtimestamp?></pubdate>
</bookinfo>

When I run `xsltproc -o /dev/null docbook.xsl lessons4lizards.xml` following error appears:

runtime error: file file:///usr/share/xml/docbook/stylesheet/nwalsh/1.72.0/lib/lib.xsl line 212 element value-of
Internal error in xsltValueOf(): failed to cast an XPath object to string.

Everything is OK when <?dbtimestamp?> is changed into <?dbtimestamp ?> (space before second question mark).

Bug are reproducible libxml2-2.6.28 and libxslt-1.1.20. (libxml2-2.6.26 and libxslt-1.1.17 are OK).

Fixed problem with xpath's string-value for a PI node with no content.  Fixed code (libxml2/xpath.c) is in SVN.  Thanks for the report.
