+ | DESCRIPTION |
+ I spent several hours trying to track down why a machine-generated stylesheet
+ would not compile successfully on Xalan. Finally someone suggested I try XT on
+ it, and I had the answer in 5 minutes.
+
+
+ The problem in the stylesheet was this:
+
+
+ [396:] <xsl:template match="table|">
+ ....
+
+
+ On XT, the result was:
+
+
+ x.xsl:396: expected node test
+
+
+ On Xalan, the result was
+
+
+ XSLT Error (javax.xml.transform.TransformerConfigurationException): null
+
+ I'm guessing that the call to insertPatternInTable() (see stack dump below) was
+ at line 146 in TemplateList.java.
+ A check here for a null StepPattern in the return from
+ [UnionPattern].getPatterns() would reveal the problem,
+ and an error return from there could produce a more informative error messeage
+ higher up.
+
+ Xalan's stack dump was:
