Code that edits XML documents

[Martin Olsson <mn...@minimum.se>]

Hi,

I need to implement a program that modifies an XML file, this file will
frequently also be edited by hand in a plain text editor. Of course, it's
important that the program does not remove or undo any of the hand-edited
changes (xml data, comments or whitespace). I have previously used Xerces
for reading XML.

What library can you recommend for editing/writing XML data? Can Xerces or
some addon do this? Is there anything in the JDK that I missed? Is there
another Apache project for this?

I'm looking for something that is simple, open source and java. Ideally I
would like something that works like this:

void updateXmlTagContent(Sometype document,
                         String xpathSayingWhichTagToUpdate,
                         String newTagContent);

Have anyone seen a library or tool that does this or something similar? It
doesnt have to be based on xpath, any solution that gets the XML document
updated will do.


rgrds,
martin

All "DOM-like" libraries would do, or ?
dom4j, jdom (two very good libraries for in-memory representation of 
the XML-tree, both support XPath, JDOM exposes children with 
java-collections) and DOM (which is a standard implemented by Xerces).
Presumably other such libraries as well as stax or xpp can do it.

They all have support for lexical-handling but that's sadly, not enough 
to have everything, for example, entities within attribute-values or 
DTD-implied attributes. Generally this means that the re-output is 
considerably less readable, at least that's my experience.

I'd love to be contradicted!
