POM reader that preserves CDATA?
Hi all, I'm working on some tooling for $dayjob that needs to manipulate POM files according to certain rules. The problem I'm running into is that some of the POMs it much manipulate contain CDATA sections, comments, etc. Also, since the modified POM often will be used as the basis for a patch file, I'd like to preserve as much of the ordering and existing whitespace in the file as possible, to minimize the patchfile size. I'm currently using the JDom-driven, Modello-generated writer, coupled with the stock XPP3-driven reader (not the best, I know). It's losing the CDATA (big problem) and injecting ^M (wrong line ending, little problem)... Does anyone have experience with this? Anyone maybe have an advanced POM reader/writer stashed somewhere that can preserve CDATA and the like?

Re: POM reader that preserves CDATA?
In general, you really can't expect to retain CDATA unless you build a DOM tree, and maybe not then. It's a fundamental principle of XML that CDATA isn't part of 'the infoset' -- the data that is represented by the file. A parser is under no obligation to faithfully report this stuff, so long as the right text ends up in the right place. However, forget xpp3 and all that ancient lumber. Use Woodstox, or the Xerces DOM, and you can probably find enough options to ask it to do what you need.

Don't we need this for the maven-release-manager anyway once we start adding arbitrary stuff?

We use decentxml in some tycho tools for bumping versions and it works well.

Re: POM reader that preserves CDATA?
You could TRY feeding the pom schema into JAXB to generate JAXB objects from it. From there, using a JAXBContext, you can call context.createBinder and then use that to unmarshall the XML DOM into JAXB objects. You can then manipulate the JAXB objects and then have it update the XML after word using the Binder. Supposedly, the binder allows semi-preserving of the infoset while using the JAXB objects. That said, I've never tried it, particularly with CDATA. :-) Dan On Tuesday, August 02, 2011 6:00:25 PM John Casey wrote: Hi all, I'm working on some tooling for $dayjob that needs to manipulate POM files according to certain rules.

Re: POM reader that preserves CDATA?
Just to confirm what Jason said. The code in question is [1] and from our testing, decentxml provides perfect read-write roundtrip without loosing any formatting anywhere in the document, including cdata, comments, whitespaces, etc, and with no special effort on our part.
