cleanup header to use variableReplace()

[menschguenther]

hey folks,

first of all. great work. i'm using docx4j for few weeks now and i am stoked.

now the reason i'm posting...

i'm trying to replace some variables in head and body of my docx.
since i want to use placeholders, i do it with

Code: Select all

variableReplace()

to make sure this will work, i clean my docx with

Code: Select all

VariablePrepare.prepare()

everythink works great for the main document part but not for the header.

to replace text i'm also using variableReplace()

eg

Code: Select all

List<SectionWrapper> sectionWrappers = wordMLPackage.getDocumentModel().getSections();

for (SectionWrapper sw : sectionWrappers) {
    HeaderFooterPolicy hfp = sw.getHeaderFooterPolicy();
    if (hfp.getDefaultHeader()!=null) {
       hfp.getDefaultHeader().variableReplace(mappings);         
    }
}


but if there is any kind of proof error, markup, rsids etc. it doesn't work.

question:
is there any simple way to 'clean' my header?

thx in advance

The VariablePrepare code shows you how it is done for the Main Document Part.

It works in 2 steps:

1. filter

2. SingleTraversalUtilVisitorCallback applied to part contents

As per the comments in the code, the filter should really be replaced with a traverse as well.

Each of these 2 steps needs to be made to apply to an arbitrary part. This is straightforward to do (and we'd accept a patch to that effect..), but I haven't done it since variable replacement isn't the recommended way to do document generation...

ok, filter is at the wrong place but it's basically not deprecated?

so i copied the code and adapted it for my header

HeaderPart header = hfp.getDefaultHeader();            
filterSettings = new WordprocessingMLPackage.FilterSettings();
filterSettings.setRemoveProofErrors(true);
filterSettings.setRemoveContentControls(true);
filterSettings.setRemoveRsids(true);
filter(filterSettings, header);

it works! but is this the right way?
