Hi all, As an important side note. I've run into a serious limitation a few times already.
Let me explain shortly what I try to do. I want to e.g. generate an XML representation of CSV data from an XQuery generator. I borrowed the schema from the CSV generator and dropped some attributes which are not useful. <?xml version="1.0" encoding="ISO-8859-1"?> <csv:document xmlns:csv="http://apache.org/cocoon/csv/1.0";> <csv:header> <csv:column>Column A</csv:column> <csv:column>Column B</csv:column> <csv:column>Column C</csv:column> </csv:header> <csv:record> <csv:field>Field A1</csv:field> <csv:field>Field B1</csv:field> <csv:field>Field C1</csv:field> </csv:record> <csv:record> <csv:field>Field A2</csv:field> <csv:field>Field B2</csv:field> <csv:field>Field C2</csv:field> </csv:record> </csv:document> Next I wrote a XSLT that transforms this into a CSV file. <?xml version="1.0" encoding="UTF-8"?> <!-- Author: Robby Pelssers This stylesheet transforms a CSV xml file into CSV --> <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; xmlns:xs="http://www.w3.org/2001/XMLSchema"; xmlns:fn="http://www.w3.org/2005/xpath-functions"; xmlns:csv="http://apache.org/cocoon/csv/1.0";> <xsl:output method="text"/> <xsl:param name="separator" as="xs:string"/> <xsl:variable name="new_line" select="'
'" /> <xsl:template match="/"> <xsl:apply-templates/> </xsl:template> <xsl:template match="csv:document"> <xsl:apply-templates select="csv:header"/> <xsl:apply-templates select="csv:record"/> </xsl:template> <xsl:template match="csv:header"> <xsl:value-of select="fn:string-join(csv:column, $separator)"/><xsl:value-of select="$new_line" /> </xsl:template> <xsl:template match="csv:record"> <xsl:value-of select="fn:string-join(csv:field, $separator)"/><xsl:value-of select="$new_line" /> </xsl:template> </xsl:stylesheet> To test if it works I wrote a little match pattern: <map:match pattern="test_csv_transformer"> <map:generate src="data/csv_generator_testdata.xml"/> <map:transform src="xslt/csv_transformer.xslt" type="saxon"> <map:parameter name="separator" value="	"/> </map:transform> <map:serialize type="text"/> </map:match> And the output works like a charm: Column A Column B Column C Field A1 Field B1 Field C1 Field A2 Field B2 Field C2 But I wanted to create a reusable transformation service and setup following pattern: <map:match pattern="csv-transformation-service/*"> <map:generate src="service-consumer:"/> <map:transform src="xslt/csv_transformer.xslt" type="saxon"> <map:parameter name="separator" value="{1}"/> </map:transform> <map:serialize type="text"/> </map:match> Unfortunately I can't call this from another cocoon block like e.g. <map:match pattern="test-csv-transformer-service"> <map:generate src="data/csv_generator_testdata.xml"/> <map:transform type="servletService"> <map:parameter name="service" value="servlet:shared:/csv-transformation-service/blabla"/> </map:transform> <map:serialize type="text"/> </map:match> The reason is that only XML is supported evidently. But is this a requirement by design or were such use cases not foreseen?!
