Subject: DOCBOOK-APPS: DocBook XML / XSL Problems (attribute tests seem alwaystrue)
Hello, I have spent several hourse on the problem I posted before and have found out that: I am not getting chapter, section, figure numbers because the test for @label will be true even if I have no label attribute in the tag. Example: a) the xml fragment: <figure><title>My Sample Figure</title> <graphic fileref="sample.jpg"/> </figure> b) the matching template that will generate the label (fragment) I have modified this to tell me whether a @label was found which will override the automatically generated id. Running it against above xml file (saxon 6.4.2, docbook xml 4.1.2) will output 'Label found:' <xsl:choose> <xsl:when test="@label"> <xsl:message> Label found: <xsl:value-of select="@label"/></xsl:message> <xsl:value-of select="@label"/> </xsl:when> <xsl:otherwise> <!-- Generate the label automatically --> </xsl:otherwise> </xsl:choose> c) working template: When I modify the line that tests for @label to read <xsl:when test="@label and not(string-length(@label)=0)"> everything works fine. The same problem occurs in several other cases (e.g. an existing but empty @scale in graphic will render as an image with a width of "%" in HTML :-( I understand that the modification of the templates is merely a way to pinpoint my problem, not the solution. I have however no idea what the solution might look like. If anyone else has this problem and a solution along with it, please drop me a line. Cheers, Ben
