Xml comparison and merge tool

Question

I need a tool for comparing and merging two xml-files.

Requirements

• Handle large Files (> 50mb)
• Collapse XmlNodes in UI
• Support validation of files
• merge files in both directions
• edit files in ui

Any suggestions?

Answer 1

I don't know an application that does exactly what you're requesting, I'm afraid, but until somebody else chips in with a better answer, two free tools I use pretty much every day, that in combination would do the trick, are:

XmlMarker DiffMerge

Answer 2

Take a look at Oxygen/XML. You can download a fully-functional 30-day trial. (No, I am not connected with the company)

Answer 3

XMLMax will do this. It allows you to load multiple large xml files in separate instances because it uses at most 20mb memory per file. you can cut/copy/paste xml fragments between the documents. You need only select the start element, then Ctrl +C will copy the entire fragment, regardless of how large it is(tested to 10Gb). treeview is extremely fast even with multi-gigabyte size files. it supports schema and dtd validation, including inline dtd. Google it: xmlmax editor. 30 day trial has not limitations.
