How can i see which attribute has an invalid value?
0%
Description
This stylesheet (the stylesheet is just an example) produces an error in line 4:
<xsl:stylesheet version="3.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<xsl:number count="aaa///bbb" from="aaa///bbb"></xsl:number>
</xsl:template>
</xsl:stylesheet>
My installed error listener is called with parameter e, an XPathException.
The only information i can retreive is this:
e.getLocator().getLineNumber() = 4
e.getMessage() = Unexpected token "/" at start of expression.
There is no indication which one of the two attributes is wrong. I tried
e.getCause() = null
e.getException() = null
e.getErrorObject() = null
There is also no information about the location of the error in the XPath expression. However, if i evaluate "aaa///bbb" using XPathCompiler, an exception SaxonApiException is thrown and getCause() (also an XPathException) gives me the actual location, via getLocator().getColumnNumber(), so that information seems to be available.
How can i tell which one of the attribute values is wrong (in Java code) and what the position of the error in the XPath expression is?
Thank you.
