Extend to Standard sdt RemovalHandler

[DaniloP]

Hi Jason,
I've followed your tips about extending the RemovalHandler.xslt;
I ended up with this, which is more similar to pseudo code... ;(

Code: Select all

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

<xsl:template match="w:sdt">
  <!--  Strips Standard content controls only. -->
    <xsl:choose>
      <xsl:when
        test="count(w:sdtPr/w:dataBinding)=1">
        <xsl:apply-templates select="w:sdtContent/node()" />
       </xsl:when>
      <xsl:otherwise>
        <xsl:copy>
          <xsl:apply-templates select="@* | node()" />
        </xsl:copy>
      </xsl:otherwise>
    </xsl:choose>
  </xsl:template>


My questions are:
-Starting from the fact that I want to remove <databinding> and related tags, I applied the w:sdtContent/node()" template (which I don't know actually how is built, because I couldn't be able to find it, but I guess, it replaces the all <w:sdt>, with just <w:sdtContent> and his childs). The same holds for the <otherwise> module applied (which, I guess, just leaves everything as it finds it). Am I wrong? Am I missing anything?
-Once I'll have the .xslt done, how do I refer to this in my code ?
I know I'm asking you to be guided step by step, but I'm really in troubles.
Thank you

Any help?

Hi Jason,
I'm still hoping to get your help.
As you suggested I tried to extend the functionality of the RemovalHandler;
The plan has been:
-Create a CustomXmlDatastoragePart and Rels;
-Add via code the xpath;
-Remove sdt's trying to leave the content;

Code: Select all


CustomXmlDataStoragePart customXmlDataStoragePart = null;
      
        try {
         customXmlDataStoragePart = new CustomXmlDataStoragePart();
      } catch (InvalidFormatException e) {
         logger.error(e);
      }
        Part parent = wordMLPackage.getMainDocumentPart() ;
       
        CustomXmlDataStorage data = null;
      try {
         data = new CustomXmlDataStorageImpl();
      } catch (InvalidFormatException e) {
         logger.error(e);
      }
       
      
      //String str = FileUtils.readFileToString(new File(xmlFilePath));
        org.w3c.dom.Document domDoc = (Document) XmlUtils.neww3cDomDocument();
      domDoc.appendChild(domDoc.createElement("FAKE_DATA_JUST_TO_CREATE_THE_PART"));
      
       
   try {
      data.setDocument(domDoc);
   } catch (Docx4JException e) {
         e.printStackTrace();
      }
      
      customXmlDataStoragePart.setData(data);
      try {
         parent.addTargetPart(customXmlDataStoragePart, AddPartBehaviour.RENAME_IF_NAME_EXISTS);
      } catch (InvalidFormatException e) {
         e.printStackTrace();
      }
      
      CustomXmlDataStoragePropertiesPart part = null;
      try {
         part = new CustomXmlDataStoragePropertiesPart();
      } catch (InvalidFormatException e) {
         e.printStackTrace();
      }
      
      org.docx4j.customXmlProperties.ObjectFactory of = new org.docx4j.customXmlProperties.ObjectFactory();
      
      DatastoreItem dsi = of.createDatastoreItem();
      String newItemId = "{" + UUID.randomUUID().toString() + "}";               
      dsi.setItemID(newItemId);
      
      part.setJaxbElement(dsi);
      
      try {
         customXmlDataStoragePart.addTargetPart(part);
      } catch (InvalidFormatException e) {
         e.printStackTrace();
      }
      
      FileInputStream xmlStream = new FileInputStream(new File(xmlFilePath));
      try {
         customXmlDataStoragePart.getData().setDocument(xmlStream); //TRUE_DATA
      } catch (Docx4JException e2) {
            logger.error(e2);
      }
      
      ClassFinder finderSdtRun = new ClassFinder(SdtRun.class); // <----- change this to suit
      new TraversalUtil(wordMLPackage.getMainDocumentPart().getContent(), finderSdtRun);
      
      System.out.println("got " + finderSdtRun.results.size()  );
      
      for (Object o : finderSdtRun.results) {
                  
         if (o instanceof SdtRun){
            
            SdtPr sdtPr=((SdtRun) o).getSdtPr();
            Tag t = sdtPr.getTag(); // cerca il tag da db e fatti restituire xpath
            
            CTDataBinding ctDataBinding = Context.getWmlObjectFactory().createCTDataBinding();
              //JAXBElement<CTDataBinding> jaxbDB = Context.getWmlObjectFactory().createSdtPrDataBinding(ctDataBinding);
              sdtPr.setDataBinding(ctDataBinding);
              ctDataBinding.setXpath("/stampaPolizzaXML[1]/contraente[1]/codiceFiscale[1]");
              ctDataBinding.setStoreItemID(dsi.getItemID());
               
            }
         Object o2 = XmlUtils.unwrap(o);
         // this is ok, provided the results of the Callback
         // won't be marshalled         
         
         
            System.out.println( XmlUtils.marshaltoString(o, true, true));
         }
      





String path = "C:/Users/danilo petrone/Desktop/Nuova Cartella/stdRemoval.xslt";
         
         
         InputStream templateStream = new FileInputStream(new File(path));
               
               //getClass().getClassLoader()
                    //.getResourceAsStream(path);
         final Source templateSource = new StreamSource(templateStream);
         
         
         Templates sdtTemplate = null;
         try {
            sdtTemplate = org.docx4j.XmlUtils.getTransformerTemplate(templateSource);
         } catch (TransformerConfigurationException e) {
            e.printStackTrace();
         }
         final JAXBResult result = prepareJAXBResult(Context.jc);
         Document mainDOM = marshaltoW3CDomDocument(((JaxbXmlPart<org.docx4j.wml.Document>) parent).getJaxbElement());
         
         org.docx4j.XmlUtils.transform(mainDOM, sdtTemplate, null, result);
         
         
         try {
            ((JaxbXmlPart<org.docx4j.wml.Document>) parent).setJaxbElement(result);
         } catch (JAXBException e) {
         }
         
      } catch (Docx4JException e2) {
         logger.error(e2);
      }
      
      

      File docx;
      try {
         docx = File.createTempFile("tmpDocx", ".docx", new File(homePath));
         Docx4J.save(wordMLPackage,docx, Docx4J.FLAG_NONE);

The .xslt is:

Code: Select all

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  xmlns:a="http://schemas.openxmlformats.org/drawingml/2006/main"

  xmlns:o="urn:schemas-microsoft-com:office:office"

  xmlns:WX="http://schemas.microsoft.com/office/word/2003/auxHint"
  xmlns:w10="urn:schemas-microsoft-com:office:word"
  exclude-result-prefixes="a aml java o pic pkg r v w wp WX w10">
 
<xsl:strip-space elements="*"/>
<xsl:output method="xml" indent="yes"/>



<xsl:template match="w:sdt">
<xsl:apply-templates select="node()|@*"/>
</xsl:template>

<xsl:template match="w:sdt/w:sdtContent">
<xsl:apply-templates select="node()|@*"/>
</xsl:template>         


<xsl:template match="w:sdt/w:sdtPr"/>
<xsl:template match="w:sdt/w:sdtEndPr"/>


 
<xsl:template match="node()|@*">
<xsl:copy>
<xsl:apply-templates select="node()|@*"/>
</xsl:copy>
</xsl:template>

</xsl:stylesheet>

The result is that I have content controls removed, but my data are removed too.
I know I'm insisting but, I really need this to work

[jason]

In the v3.3.0 branch, I've changed semantics of Quantifier.ALL; it now really means remove all content controls, whether OpenDoPE or not.

See https://github.com/plutext/docx4j/commi ... 11bbc9471c

You can check that branch out and build/use it; see announces/docx4j-3-3-0-dev-builds-t2262.html

Thank you so much Jason!
Now the procedure is:
-Create a CustomXMLDataStorage and related properties-> populate it with your own data;
-Insert Xpaths via code;
-Save the docx;
-Open it again;
-Create BindingHandler-> Bind the data;
-Create RemovalHandler->Remove sdt's;
-Save the docx once again.
Now you have your data inserted and the content control removed.
Ready to convert it!
