How to replace variables in footer using docx4j?

[siva kumar]

Hi jason,
The normal way of replacing variables is not working for footer variable replacement, can u pls add some sample code to do that
im using below code for replacement

-----------------------------
MainDocumentPart documentPart = wordMLPackage.getMainDocumentPart();

// unmarshallFromTemplate requires string input
String xml = XmlUtils.marshaltoString(documentPart.getJaxbElement(),
true);
obj = XmlUtils.unmarshallFromTemplate(xml, mappings);
------------------------------

Thanx in advance




Regards,
Siva Kumar

Get each footer using the document model, or by iterating through the parts looking for parts of type footer.

For example, MailMerger does the following (headers/footers in first document section only):

Syntax: [ Download ] [ Hide ]

Syntax: [ Download ] [ Show ]

Using java Syntax Highlighting

                        SectionWrapper sw = input.getDocumentModel().getSections().get(0);
                        SectPr sectPr = sw.getSectPr();
                       
                        List<CTRel> hdrFtrRefs = sectPr.getEGHdrFtrReferences();
                        titlePage = sectPr.getTitlePg();
                       
                        for (CTRel rel : hdrFtrRefs) {
                                String relId = rel.getId();
                                log.debug("for h|f relId: " + relId);
                               
                                JaxbXmlPart part = (JaxbXmlPart)input.getMainDocumentPart().getRelationshipsPart().getPart(relId);
                                :
                        }

Hi Jason,

I'm getting below error while replacing variables in footer at the last line of code "footerPart.setJaxbElement((Ftr)obj);" . pls check

"java.lang.NullPointerException"

#CODE:
-----------------------
List<SectionWrapper> sectionWrappers = wordMLPackage.getDocumentModel().getSections();
String xml = null;
for (SectionWrapper sw : sectionWrappers) {
HeaderFooterPolicy hfp = sw.getHeaderFooterPolicy();
if (hfp != null) {
FooterPart footerPart = hfp.getDefaultFooter();
if (footerPart != null) {
//xml --> string
xml = XmlUtils.marshaltoString(footerPart.getJaxbElement(), true);
System.err.println(xml);
}

HashMap<String, String> mappings = new HashMap<String, String>();
mappings.put("testing footer", "${test}");
Object obj = null;
try {

obj = XmlUtils.unmarshallFromTemplate(xml, mappings);
Ftr ftr = (Ftr)obj;
System.err.println(ftr.getContent().toString());
} catch (JAXBException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

// Inject result into docx
footerPart.setJaxbElement((Ftr)obj);
-----------------------

[jason]

well, is hfp.getDefaultFooter() returning null?

What footers do you have in the relevant section?

You can run the sample https://github.com/plutext/docx4j/blob/ ... rList.java to find out
