Note Submitter: Sandro_dot_Zic@oc4-science_dot_org ---- This shows how to use xslt_run to add dynamic content to the result tree, i.e. how to hand over parameters to the XSL stylesheet and write to Sablotron's document buffer. First, assign the value of a parameter to an array: $xslt_params["test"] = "Run-time parameter."; The parameter is envoced in XSL by <xsl:value-of select="$test" /> Don't forget to define the parameter at the beginning of your stylesheet: <xsl:param name="test"/> How can we add dynamic content from a database to the XSLT output? In Sablotron, this is done using the document buffer function. Retrieve a table's content, store it in a XML structure assigned to an array: $xslt_args["buffer1"] = " <TestBuffer> <Message> <Content> This is message 1 of buffer 1. </Content> </Message> <Message> <Content> This is message 2 of buffer 1. </Content> </Message> </TestBuffer> "; This is how you add the buffer to the result tree in your XSL document: <xsl:for-each select="document('arg:/buffer1')/TestBuffer/Message"> <xsl:value-of select="Content" /> </xsl:for-each> Now, use xslt_run to start processing an XML file, the parameter, and the document buffer: $processor = xslt_create(); xslt_run ($processor, "file://".$DOCUMENT_ROOT.$xsl_file, "file://".$DOCUMENT_ROOT.$xml_file, "arg:/_result", $xslt_params, $xslt_args); $result = xslt_fetch_result ($processor); echo $result; The complete XSL file looks like this: <?xml version="1.0" encoding="iso-8859-1"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> <xsl:output method="html" version="1.0" standalone="yes" indent="yes" /> <!-- define parameter --> <xsl:param name="test"/> <xsl:template match="/"> <!-- run-time parameter --> <xsl:value-of select="$test" /> <!-- dynamic content --> <xsl:for-each select="document('arg:/buffer1')/TestBuffer/Message"> <xsl:value-of select="Content" /> </xsl:for-each> <!-- content from XML file --> ... </xsl:template> </xsl:stylesheet>
