context:-URL-Protokoll

With the context: URL protocoll, you can access variables in XSL mappings that have been defined using the variable element and placed before the XSL mapping element in the process at runtime of a process. The document stored in the variable can be integrated in the XSL mapping via the document() function.

Note:

When processed in the process, the document() function does not return an error message if access to the variable fails, for example, due to a typing error or because the variable was not created with the PUT option.

Structure of the URL

The URL should be structured according to the following pattern (slashes after the URL handler may be problematic):

HTML/XML

context:Variablenname

An XSL mapping using this URL protocol cannot be executed in the transformation preview of the Mapping Editor.

Example

In this example, the variable Var was created via a Variable process component in a process that also contains the following XSL mapping. This variable stores an XML document that is read in the XSL mapping via the document() function and cached in a DocVar XSL variable. Their nodes can be selected as desired via XPath.

HTML/XML

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
   <xsl:output encoding="UTF-8" method="xml" version="1.0"/>
   <xsl:template match="/">
      <result>
         <xsl:variable select="document('context:Var')" name="DocVar"/>
         <xsl:value-of select="$DocVar/child::ElemName"/>
      </result>
   </xsl:template>
</xsl:stylesheet>
