Hi everybody, I have a problem with XSL transformations and I cannot reach a solution, maybe someone has a more clear view about this problem. I've this XSL function to parse a date and transform it in the format I need, it is done via regular expressions: <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:my="my://own.uri"> ... <xsl:function name="my:date-formatx"> <xsl:param name="datexx" as="xs:string" /> <xsl:analyze-string select="$datexx" regex="(\d{{4}})-(\d{{2}})-(\d{{2}})(\s*)"> <xsl:matching-substring> <xsl:variable name="grupo1"><xsl:value-of select="regex-group(1)"/></xsl:variable> <xsl:variable name="grupo2"><xsl:value-of select="regex-group(2)"/></xsl:variable> <xsl:variable name="grupo3"><xsl:value-of select="regex-group(3)"/></xsl:variable> <xsl:value-of select="concat($grupo1, $grupo2, $grupo3)"/> </xsl:matching-substring> </xsl:analyze-string> </xsl:function> ... I´ve tried, doing it with SmooksAction, Smooks Transformer, doing the XSL transformation nativelly from the ESB with the code I found here: http://www.jboss.org/community/docs/DOC-10336, and my last try was using the same code but with SAXON Transformer insteand of javax.xml.transform.Transformer, and I get the same error for all. I've another project only with Smooks and the entire XSL transformation is executed correctly there, but now, when I put it into an ESB action I get that the function "regex-group" is not defined. Here's the exception: ("No se ha podido encontrar la funci¾n: regex-group" is "Unable to find the function: regex-group" in spanish :) org.jboss.soa.esb.actions.ActionProcessingException: javax.xml.transform.TransformerConfigurationException: javax.xml.transform.TransformerException: javax .xml.transform.TransformerException: No se ha podido encontrar la funci¾n: regex-group at nativeXSL.XSLActionProcessor.process(XSLActionProcessor.java:90) at org.jboss.soa.esb.listeners.message.ActionProcessingPipeline.process(ActionProcessingPipeline.java:316) at org.jboss.soa.esb.listeners.message.MessageAwareListener$TransactionalRunner.run(MessageAwareListener.java:530) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:650) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:675) at java.lang.Thread.run(Thread.java:595) Caused by: javax.xml.transform.TransformerConfigurationException: javax.xml.transform.TransformerException: javax.xml.transform.TransformerException: No se ha podido encontrar la funci¾n: regex-group at org.apache.xalan.processor.TransformerFactoryImpl.newTemplates(TransformerFactoryImpl.java:936) at org.apache.xalan.processor.TransformerFactoryImpl.newTransformer(TransformerFactoryImpl.java:774) at nativeXSL.SAXONTransformer.transform(SAXONTransformer.java:25) at nativeXSL.XSLActionProcessor.process(XSLActionProcessor.java:83) ... 5 more Caused by: javax.xml.transform.TransformerException: javax.xml.transform.TransformerException: No se ha podido encontrar la funci¾n: regex-group at org.apache.xalan.processor.TransformerFactoryImpl.newTemplates(TransformerFactoryImpl.java:928) ... 8 more Caused by: javax.xml.transform.TransformerException: No se ha podido encontrar la funci¾n: regex-group at org.apache.xalan.processor.XSLTAttributeDef.processEXPR(XSLTAttributeDef.java:768) at org.apache.xalan.processor.XSLTAttributeDef.processValue(XSLTAttributeDef.java:1404) at org.apache.xalan.processor.XSLTAttributeDef.setAttrValue(XSLTAttributeDef.java:1600) at org.apache.xalan.processor.XSLTElementProcessor.setPropertiesFromAttributes(XSLTElementProcessor.java:338) at org.apache.xalan.processor.XSLTElementProcessor.setPropertiesFromAttributes(XSLTElementProcessor.java:263) at org.apache.xalan.processor.ProcessorTemplateElem.startElement(ProcessorTemplateElem.java:76) at org.apache.xalan.processor.StylesheetHandler.startElement(StylesheetHandler.java:623) at org.apache.xerces.parsers.AbstractSAXParser.startElement(Unknown Source) at org.apache.xerces.parsers.AbstractXMLDocumentParser.emptyElement(Unknown Source) at org.apache.xerces.impl.XMLNSDocumentScannerImpl.scanStartElement(Unknown Source) at org.apache.xerces.impl.XMLDocumentFragmentScannerImpl$FragmentContentDispatcher.dispatch(Unknown Source) at org.apache.xerces.impl.XMLDocumentFragmentScannerImpl.scanDocument(Unknown Source) at org.apache.xerces.parsers.XML11Configuration.parse(Unknown Source) at org.apache.xerces.parsers.XML11Configuration.parse(Unknown Source) at org.apache.xerces.parsers.XMLParser.parse(Unknown Source) at org.apache.xerces.parsers.AbstractSAXParser.parse(Unknown Source) at org.apache.xerces.jaxp.SAXParserImpl$JAXPSAXParser.parse(Unknown Source) at org.apache.xalan.processor.TransformerFactoryImpl.newTemplates(TransformerFactoryImpl.java:920) ... 8 more 23:07:26,389 WARN [ActionProcessingPipeline] No fault address defined for fault message!
