How can I validate a large XML file (>100mb)? I try to open it with IE, FX & GC and it either crashes or doesn\'t do anything.
The only tool I know that combines a large file viewer and an XML validator for huge files is XML ValidatorBuddy . The file viewer doesn't load the complete file at once but it is possible to scroll and there is also XML syntax-coloring applied. The validation uses the SAX parser from Xerces and your document with >100mb shouldn't be a problem.
