| I have a XSLT page to transform a.xml as well as an XML | file referenced by document('b.xml') | | in the XSLT program, i wrote: | | <xsl:template match="/"> <!-- the root of a.xml --> | | <xsl:for-each select="document('b.xml')/root/subroot"/> | <!-- here I want to reference to both | the nodes under EACH "subroot" of b.xml | and the nodes that are under the "/"node of a.xml> | </xsl:for-each> | | </xsl:template> | | how can i change context inside <xsl:for-each>? (better without the help | of variable/param) I think the most straightforward way is actually to use a variable to capture the "a.xml" primary source document. In fact, while you're at it, why not capture both "a.xml" and "b.xml" in variables, so you can do: <xsl:template match="/"> <!-- the root of a.xml --> <!-- Put a.xml (primray) and b.xml (secondary) sources in a variable --> <xsl:variable name="a" select="/" /> <xsl:variable name="b" select="document('b.xml')" /> <xsl:for-each select="$b/root/subroot"/> <!-- Here you can select="a$/foo/bar" to refer to nodes from a.xml --> </xsl:for-each> </xsl:template> For even better overall stylesheet clarity/readability, you could promote the two variables above to be top-level stylesheet variables and in doing so make it very clear what source documents the current stylesheet operates on. Of course this is only possible if the "b.xml' you're giving in your sample is a fixed name, and not -- in your actual stylesheet -- derived by some function of the input from a.xml. But you get the idea... _____________________________________________________________________ Steve Muench - Developer, Product Manager, XML Evangelist, Author "Building Oracle XML Applications" - www.oreilly.com/catalog/orxmlapp XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
