Can I read bookmark from word document

[Vipin]

I am looking to read bookmark from the word documents. It there a way I can use this API to read those.

[jason]

Sure, they are represented by org.docx4j.wml.CTBookmark; you'll find them in Body.getEGBlockLevelElts and P (ie paragraph) amongst other places (eg in tables).

[jason]

Here is some text I wrote a while ago on this, and thought I may as well post in this thread for posterity.

For me, they end up as org.docx4j.wml.CTBookmark and org.docx4j.wml.CTMarkupRange respectively.

I made a simple document, which contains:

Code: Select all

<w:bookmarkStart w:id="0" w:name="mybookmark"/><w:r><w:t>stuff</w:t></w:r><w:bookmarkEnd w:id="0"/>

They became:

Code: Select all

javax.xml.bind.JAXBElement
      {http://schemas.openxmlformats.org/wordprocessingml/2006/main}bookmarkStart <----- (JAXBElement)o).getName()
      org.docx4j.wml.CTBookmark <----- (JAXBElement)o).getDeclaredType().getName()

  javax.xml.bind.JAXBElement
      {http://schemas.openxmlformats.org/wordprocessingml/2006/main}bookmarkEnd <----- (JAXBElement)o).getName()
      org.docx4j.wml.CTMarkupRange <----- (JAXBElement)o).getDeclaredType().getName()


You should be able to do something like:

Code: Select all

                if ( ((JAXBElement)o).getName().getLocalPart().equals("bookmarkStart") ) {
                    org.docx4j.wml.CTBookmark bs = (org.docx4j.wml.CTBookmark)((JAXBElement)o).getValue();
                    System.out.println(" .. bookmarkStart" );
                }
               
                if ( ((JAXBElement)o).getName().getLocalPart().equals("bookmarkEnd") ) {
                    org.docx4j.wml.CTMarkupRange be = (org.docx4j.wml.CTMarkupRange)((JAXBElement)o).getValue();
                    System.out.println(" .. bookmarkEnd" );
                }


The relevant part of the XSD is:

Code: Select all

    <xsd:group name="EG_RangeMarkupElements">
        <xsd:choice>
            <xsd:element name="bookmarkStart" type="CT_Bookmark">
                <xsd:annotation>
                    <xsd:documentation>Bookmark Start</xsd:documentation>
                </xsd:annotation>
            </xsd:element>
            <xsd:element name="bookmarkEnd" type="CT_MarkupRange">
                <xsd:annotation>
                    <xsd:documentation>Bookmark End</xsd:documentation>
                </xsd:annotation>
            </xsd:element>


which is why they end up as org.docx4j.wml.CTBookmark and org.docx4j.wml.CTMarkupRange respectively.

I determined the CTBookmark and CTMarkupRange objects in my document but how do I receive the text that is bookmarked (I think "stuff" in the example)?

[jason]

The bookmark start and end tags are point tags, so in XML, there is nothing "inside" as such. The start tag could be in one paragraph, and the end tag in another.

If you can assume the tags are in a single paragraph, you could get the contents by iterating through the paragraph contents.

Another way to do it would be to marshal to string, and use string operations to get the substring between the bookmark tags.

What do you want to do with the stuff between the tags? Text extraction? You could use something like TextUtils.extractText

Please let us know how you end up tackling this, anyone with a better approach, please speak up

[ostkurve]

Thanks for the reply, Jason.
Your guess was right, I want to extract the text that is bookmarked. In my case the bookmark does not spread paragraphs so the text is inside one and the same paragraph. However I don't see how I can navigate to the paragraph object when I encounter CTBookmark or CTMarkupRange ...

[jason]

Given a p which you expect bookmark start and end tags, a quick sketch of one approach, untested, adapted from OpenMainDocumentAndTraverse sample:

Code: Select all

   StringBuffer sb = new StringBuffer();
   boolean inBookmark = false;
   
   void walkList(List children){
            
      for (Object o : children ) {               
         if ( o instanceof javax.xml.bind.JAXBElement) {
            
            System.out.println( "\n" + XmlUtils.JAXBElementDebug((JAXBElement)o) );

            if ( ((JAXBElement)o).getName().getLocalPart().equals("bookmarkStart") ) {
               //org.docx4j.wml.CTBookmark bs = (org.docx4j.wml.CTBookmark)((JAXBElement)o).getValue();
               System.out.println(" .. bookmarkStart" );
               inBookmark = true;
            }
            
            if ( ((JAXBElement)o).getDeclaredType().getName().equals("org.docx4j.wml.Text") ) {
               
               org.docx4j.wml.Text t = (org.docx4j.wml.Text)((JAXBElement)o).getValue();
               
               if (inBookmark) {
                  sb.append( t.getValue() );
               }               
            }             
            
            
            if ( ((JAXBElement)o).getName().getLocalPart().equals("bookmarkEnd") ) {
               //org.docx4j.wml.CTMarkupRange be = (org.docx4j.wml.CTMarkupRange)((JAXBElement)o).getValue();
               System.out.println(" .. bookmarkEnd" );
               inBookmark = false;
            }
            
         } else {
            System.out.println("  " + o.getClass().getName() );
            if ( o instanceof org.docx4j.wml.R) {
               org.docx4j.wml.R  run = (org.docx4j.wml.R)o;
               walkList(run.getRunContent());                           
            }
         }
//         else if ( o instanceof org.docx4j.jaxb.document.Text) {
//            org.docx4j.jaxb.document.Text  t = (org.docx4j.jaxb.document.Text)o;
//            System.out.println("      " +  t.getValue() );               
//         }
      }
   }


Pass in p.getParagraphContent()

how I can navigate to the paragraph object when I encounter CTBookmark or CTMarkupRange

The wml package classes each have a method getParent(), so you should be able to get from CTBookmark to P.

Is that what you meant?

[novato]

Hello Jason

I'm trying to find Bookmark and P. I found the CTBookmark but I am not able to get P with getParent ()

The wml package classes each have a method getParent(), so you should be able to get from CTBookmark to P.

The error is:

java.lang.ClassCastException: javax.xml.bind.JAXBElement cannot be cast to org.docx4j.wml.P

my code:

Code: Select all

public static org.docx4j.wml.P findBookmarkedP(String name, MainDocumentPart documentPart) throws JAXBException {
   
    final String xpath = "//w:bookmarkStart";

    List<Object> objects = documentPart.getJAXBNodesViaXPath(xpath, false);

    CTBookmark ctb = (CTBookmark) XmlUtils.unwrap(objects.get(1));
    String hh = ctb .getName();
    P p = (P) ctb .getParent();

    return p;
}


Can you help me?
thank you

Can anyone help me? I'm lost ..............

Thanks

[Nanocom]

Code: Select all

Try to figure out what is the class of the parent (getClass())

[novato]

Thank you very much for the answer.

Sorry, my English is bad, my JAVA is bad and my docx4j is bad ..........................

You can write an example.

Thank

You may be experiencing the bug discussed at docx-java-f6/get-r-for-a-text-node-t403.html

You might need to use TraversalUtil instead. Here is some code:
