http://nagoya.apache.org/bugzilla/show_bug.cgi?id=22102 XPATH not performing implicit conversion from int to boolean as expected Summary: XPATH not performing implicit conversion from int to boolean as expected Product: XalanJ2 Version: 2.3 Platform: PC OS/Version: Windows NT/2K Status: NEW Severity: Normal Priority: Other Component: Xalan AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] Using Xalan version 2.3.1 as distributed with Netbeans 3.5. It appears that the implicit conversion of certain types to booleans does not work as expected. We have a stylesheet with the following template matching logic. <xsl:template match="record[normalize-space(field)]"> This correctly evaluates the template if the node record/field contained a non- empty string. We discovered that performing the following always evaluated to false: <xsl:template match="record[string-length(normalize-space(field))]"> Given that string-length() returns 0 for empty strings, should this not be implicitly converted to a boolean 'false'? Especially as the following works as expected: <xsl:template match="record[boolean(string-length(normalize-space(field)))]"> The problem we saw was that the implicit conversion from int to boolean did not seem to take place in this case.
