XSL Param with XPath expressions

1 New Member
Hi !

I'm making a XSL that returns distinct values from a XML Element, but the element is dynamic, so i pass it from the server as a Parameter.

XSL:

Expand|Select|Wrap|Line Numbers
  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  3. <xsl:output method="xml" />
  4.  
  5. <xsl:param name="puff" />
  6. <Element>
  7.     <xsl:template match="/">            
  8.         <xsl:for-each select="//$puff[not(.=preceding::$puff)]">
  9.             <value><xsl:value-of select="." /></value>        
  10.         </xsl:for-each>
  11.  
  12.     </xsl:template>
  13.  
  14. </Element>
  15. </xsl:stylesheet>
It gives me syntax error when i use the param in the xpath expressions.. any solution? Thanks in advance

hi I thought that this would be easy, but maybe not so much. I want to: pass an xpath expression and a string value to a stylesheet and copy the source xml document, changing the value of the node described by the xpath expression, to the new value.

Hi all, I got a JSP using JSTL to transform XML to HTML, and I want to pass a variable "statusFilter" into the XSL. e.g. <x:parse xml="${xml}" var="doc" /> <x:transform xml="${doc}" xslt="${xslt}"> <x:param name="statusFilter"> ABCD </x:param>

The definition of XPath 1.0 says "A QName in the node test is expanded into an expanded-name using the namespace declarations from the expression context. This is the same way expansion is done for element type names in start and end-tags except that the default namespace declared with xmlns is not used: if the QName does not have a prefix, then the namespace URI is null (this is the same way attribute names are expanded). It is an error...

Are there any quick, reliable shortcuts to determine if two arbitrary XPath expressions yield result sets that intersect? The obviously way would be to iterate over the set of nodes from one expression, checking each one to see if it's also contained in the other set, but I'm wondering if there might be ways of doing this by looking at or rewriting the actual XPath expressions themselves, without evaluating them.

Hello everybody, I have a question concerning XPath expressions and namespaces.

Hi, I have been trying for several days to read XML files into my program. I have been following several good tutorials on the internet, but I am struggling because the particular XML files that I am reading have several nested fields: <?xml version="1.0" encoding="UTF-8" ?> <xml> <records> <record> <database name="test.enl">test</database> <contributors> <authors> <author>
