Pass xml document as parameter to xsl

java, saxon, xalan, xml, xslt

Solution

I was able to get it work with Saxon see below code. I think the key was the document.getDocumentElement() as parm

      public String transformResultXML(String xmlSource, Templates xsl,String policyXml )    {
       String result = "";  

    try {

          StringWriter writer = new StringWriter();
          StringReader reader2 = new StringReader(policyXml);

          DocumentBuilderFactory dfactory =
                  DocumentBuilderFactory.newInstance( "com.icl.saxon.om.DocumentBuilderFactoryImpl",null);

          dfactory.setNamespaceAware(true);

          DocumentBuilder docBuilder = dfactory.newDocumentBuilder();

          org.w3c.dom.Document document = docBuilder.parse(new InputSource(new StringReader(xmlSource)));

          Transformer transformer = xsl.newTransformer();

          transformer.setParameter("RsXml", document.getDocumentElement());

          transformer.setOutputProperty(OutputKeys.INDENT, "yes");
          transformer.transform(new javax.xml.transform.stream.StreamSource(reader2),
                  new javax.xml.transform.stream.StreamResult(writer));
          result = writer.toString();
          System.out.println(result);

    } catch( Exception e ) {
        e.printStackTrace();
    }

XSL snippet

    <xsl:param name="RsXml" />

<xsl:template match="/policy/vehicles">


        <xsl:for-each select="$RsXml/InsuranceSvcRs/com.csc_PolicyOrderCurrentCarrierInqRs/PersVeh">

Problem

I have read a lot of post and tried a lot of things but still can't get the xsl to find values in the parameter. I started with java's sun xalan and never got it working so I switched to saxon to no avail. I want to combine two xml docs into one with xls. Never are on a file system, this is for a web app that builds xml strings/ docs. I have tried passing an DTMAxisIterator, DomSource , Doc to Node set in xsl, string. It worked fine in NotePad++ with an xsl document() but I don't want to save the xml on the system. XSL ``` <xsl:param name="RsXml" select="/"/> <xsl:template match="/policy/vehicles"> <vehicle type="DP" type_code="DP"/> <xsl:for-each select="$RsXml/InsuranceSvcRs /com.csc_PolicyOrderCurrentCarrierInqRs/PersVeh"> <vin> <xsl:value-of select="VehIdentificationNumber"/> </vin> <veh_year> <xsl:value-of select="ModelYear"/> </veh_year> <make> <xsl:value-of select="Manufacturer"/> </make> <model> <xsl:value-of select="Model"/> </model> <costnew> <xsl:value-of select="CostNewAmt/Amt"/> </costnew> <symbol> <xsl:value-of select="VehSymbolCd"/> </symbol> <wheregaraged></wheregaraged> <liabilityonly></liabilityonly> <collision></collision> <comprehensive></comprehensive> <rentalreimbursement></rentalreimbursement> <towing></towing> <altered></altered> <title></title> <enginesize> <xsl:value-of select="NumCylinders"/> </enginesize> <trailertype/> <trtonnage/> <mctype/> <mcenginecc/> <vehicleuse></vehicleuse> <mhawnings></mhawnings> <vseat15></vseat15> <vseat15text/> <extraequipment></extraequipment> <mcsidecar></mcsidecar> <atvwheels/> <damage/> <endorsements/> <avtotal/> <v_underwriting> <altered></altered> <alteredlist/> <alteredexplain/> <businessuse></businessuse> <haulstudents></haulstudents> <pulltrailers></pulltrailers> <trailerendorsement/> </v_underwriting> <driverid></driverid> <gen_classcode></gen_classcode> <classcode></classcode> <primary_veh></primary_veh> <rates> <bi></bi> <pd></pd> <med></med> <ubi></ubi> <upd></upd> <comp></comp> <coll></coll> <comm></comm> <rr></rr> <tl></tl> </rates> <xferdis></xferdis> <atv_young_dr></atv_young_dr> <mrcd_date/> <hasdamage></hasdamage> <comp_symbol></comp_symbol> <str_legal></str_legal> <addresses/> </xsl:for-each> <xsl:apply-templates/> ``` XML One ``` <?xml version="1.0" encoding="UTF-8"?> <policy id="1735"> <vehicles> </vehicles> </policy> ``` XML Two ``` <ACORD> <InsuranceSvcRs> <com.csc_PolicyOrderCurrentCarrierInqRs> <PersVeh id="001"> <ItemIdInfo> <InsurerId>001</InsurerId> </ItemIdInfo> <Manufacturer>FORD</Manufacturer> <Model>WINDSTAR</Model> <ModelYear>1999</ModelYear> <VehBodyTypeCd>ES</VehBodyTypeCd> <CostNewAmt> <Amt>23660</Amt> </CostNewAmt> <NumDaysDrivenPerWeek /> <EstimatedAnnualDistance> <NumUnits /> <UnitMeasurementCd /> </EstimatedAnnualDistance> <FullTermAmt> <Amt /> </FullTermAmt> <TerritoryCd /> <VehIdentificationNumber>1</VehIdentificationNumber> <NumCylinders>6</NumCylinders> <VehSymbolCd /> <AntiLockBrakeCd>4-WHEEL STD</AntiLockBrakeCd> <DaytimeRunningLightInd /> <DistanceOneWay> <NumUnits /> <UnitMeasurementCd>MI</UnitMeasurementCd> </DistanceOneWay> <AntiTheftDeviceCd>PASS-KEY</AntiTheftDeviceCd> <VehPerformanceCd /> <VehUseCd /> <AirBagTypeCd>BOTH</AirBagTypeCd> <com.csc_VehBodyTypeFreeformInd /> </PersVeh> </com.csc_PolicyOrderCurrentCarrierInqRs> </InsuranceSvcRs> </ACORD> ``` Class ``` public String transformResultXML(String xmlSource, Templates xsl,String policyXml ) { String result = ""; try { StringWriter writer = new StringWriter(); StringReader reader2 = new StringReader(policyXml); XmlHelper xh = new XmlHelper(); Document xmlSrc = xh.loadDoc(xmlSource); DOMSource source = new DOMSource(xmlSrc); ByteArrayInputStream byteStream = new ByteArrayInputStream(xmlSource.getBytes()); StringReader reader = new StringReader(xmlSource); SAXSource source2 = new SAXSource(new XMLFilterImpl(), new InputSource(reader)); TransformerFactory transFact = new com.icl.saxon.TransformerFactoryImpl(); Transformer transformer = transFact.newTransformer(); transformer.setParameter("RsXml",source2); // transformer.setParameter("RsXml",xmlSrc); transformer.setOutputProperty(OutputKeys.INDENT, "yes"); transformer.transform(new javax.xml.transform.stream.StreamSource(reader2), new javax.xml.transform.stream.StreamResult(writer)); result = writer.toString(); System.out.println(result); } catch( Exception e ) { e.printStackTrace(); } return result; } ```
