How to process docx to replace bold tags

[gizwhu]

I am converting docx to html and currently bold texts are not converted correctly.

The following is in the document.xml before conversion

Code: Select all

<w:tr>
   <w:trPr/>
   <w:tc>
      <w:tcPr>
         <w:tcW w:w="9016" w:type="dxa"/>
         <w:gridSpan w:val="4"/>
      </w:tcPr>
      <w:p>
         <w:pPr>
            <w:ind w:left="0" w:firstLine="0" w:right="95"/>
            <w:rPr>
               <w:rFonts w:ascii="Arial" w:hAnsi="Arial" w:cs="Arial"/>
               <w:szCs w:val="24"/>
            </w:rPr>
         </w:pPr>
         <w:r>
            <w:rPr>
               <w:rFonts w:ascii="Arial" w:hAnsi="Arial" w:cs="Arial"/>
               <w:b w:val="on"/>
               <w:bCs w:val="on"/>
               <w:szCs w:val="24"/>
               <w:lang w:val="en-SG" w:eastAsia="en-GB"/>
            </w:rPr>
            <w:t xml:space="preserve">BOLD TEXT</w:t>
         </w:r>
      </w:p>
   </w:tc>
</w:tr>


Apparently the following works :

Code: Select all

<w:tr>
   <w:trPr/>
   <w:tc>
      <w:tcPr>
         <w:tcW w:w="9016" w:type="dxa"/>
         <w:gridSpan w:val="4"/>
      </w:tcPr>
      <w:p>
         <w:pPr>
            <w:ind w:left="0" w:firstLine="0" w:right="95"/>
            <w:rPr>
               <w:rFonts w:ascii="Arial" w:hAnsi="Arial" w:cs="Arial"/>
               <w:szCs w:val="24"/>
            </w:rPr>
         </w:pPr>
         <w:r>
            <w:rPr>
               <w:rFonts w:ascii="Arial" w:hAnsi="Arial" w:cs="Arial"/>
               <w:b/>
               <w:bCs/>
               <w:szCs w:val="24"/>
               <w:lang w:val="en-SG" w:eastAsia="en-GB"/>
            </w:rPr>
            <w:t xml:space="preserve">BOLD TEXT</w:t>
         </w:r>
      </w:p>
   </w:tc>
</w:tr>


My question is, how do i process the docx to find all <w:b w:val="on"/> and replace it with <w:b/> ?

Note that a third party processor could choose to use 'on' or 'off', even where Word doesn't. This would cause trouble.

It seems that Sun/Oracle JAXB in Java 1.8.0_05 quietly converts an illegal value such as "on", to "false".

MOXy, on the other hand, detects it as an issue:

So if you use MOXy, custom-preprocessor.xslt or mc-preprocessor.xslt could be used to fix the XML.

What software was used to create this docx?

[gizwhu]

This docx is generated by a document template generator called "WindWard".

In my case, I did notice that Jaxb is quietly converting the value to false. Unfortunately I require this value to be true.

[jason]

The most expedient way to handle this is to use MOXy as your JAXB implementation, which is just a matter of adding:

Then add a rule to org/docx4j/jaxb/mc-preprocessor.xslt to change "on" to 1 or true. Its better to copy mc-preprocessor.xslt to say mc-preprocessor-custom.xslt then make the change there. Tell docx4j about this via docx4j property "docx4j.jaxb.JaxbValidationEventHandler":

How do I "Tell docx4j about this via docx4j property "docx4j.jaxb.JaxbValidationEventHandler""?

I am using the following https://github.com/plutext/docx-html-editor

[jason]

Include it in a docx4j.properties file on your classpath; an example is at https://github.com/plutext/docx4j/blob/ ... rties#L109
