Validator and editor for huge XML data

Open large XML data and validate even multi-GB files directly in the application. XML Validator Buddy can handle huge XML input, where other tools just stop working. Use the Explorer window to validate those XML documents with a single click without the necessity of reading the whole content at once. If the XML has no schema assigned, XML ValidatorBuddy can use any W3C schema or DTD to run the validator. After validation, take a closer look at all reported errors in the Large-File editor window and use the jump-to-error functionality which, of course, also works for huge XML data.
