CodePudding user response：

You can't use information unknown in the XSL stage. A page number is only known during the composition phase not the transformation to XSL FO.

You can only look to composing to the FO processors intermediate format and then applying a new transformation to it to use the data.

In your example you do not give any information as to why you need it as a variable. If you only want it printed then you should just use fo:page-number.

CodePudding user response：

if you define

<fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:pdf="http://xmlgraphics.apache.org/fop/extensions/pdf" font-family="auto">

you can use xsl tag in code.
