"I found XMLMax to be a very quick and easy way to view large (~2GB) XML files." Stephen Cann, Uptick Data, San Francisco.

Performance.   XMLMax displays a 3 GB XML in the treeview in about 20 seconds. Re-opening takes under two seconds using a tiny meta file created when first opened. Our text viewer lets you browse the entire raw XML of any size file instantly.

XML Syntax Errors.  If your XML is not well-formed[has syntax errors] it is essentially unusable. XML compliant software will not read it. XML is a standard with many syntax rules. XMLMax uses the Microsoft XmlReader to identify any syntax error (XmlException) and opens the XML(any size) in a text editor at the reported error so you can fix it.

Schema Validation Errors.  XML that is not valid may be rejected by other XML software or your business partners if they require schema validation. XMLMax provides a complete solution that validates the entire document in one pass, lists all the errors with a GoTo function to edit and fix each one. It supports DTD, multiple schema files and creation of a schema from the XML.

Illegal Characters  XMLMax includes a tool that globally removes or replaces characters not allowed in XML, as per the W3C XML specification.

DateTime Format.  XMLMax can globally convert date and time strings to XML datetime format (ISO 8601), or remove them.

Searching.  Text search with global replace in any size file, with XML-specific options. Limit hits to specific node types or an XML path. No indexing or pre-compilation.

Text Editor Risks. A text editor does not syntax check, validate, detect or block illegal XML characters or prevent you from altering the XML markup. XMLMax does.

Return On Investment. XMLMax saves time and money. It eliminates custom programming by solving many problems automatically. Its speed reduces processing time. With its low price, it can easily pay for itself the first time used.
