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. XPATH and XSLT are provided for files that can be loaded into memory.

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 all this and more.

Return On Investment.  XMLMax eliminates custom programming by solving many problems automatically. Its speed reduces processing time. It can easily pay for itself the first time used.

Huge XML File

AGM, makers of InterLink, wrote to tell us they used XMLMax with a 270 GB(29 GB compressed) Open Street Map XML file (http://download.geofabrik.de/europe-latest.osm.bz2). So we tried it too, both browsing and saving some edits. A fast processor and drives are recommended for such large files, but only 500 MB available RAM are needed because of our file segmenting and buffering.

What's New

Current version: 4.0

The save process was changed to no longer make a copy of the XML file, and instead update the meta file. This saves significant time and disk space and it is no longer necessary to re-open the XML file after saving, even when performing a search or validation. When the file is re-opened, the meta file is used so the entire XML does not have to be parsed again.

Save File now prompts for an alternate location if the target location has insufficient disk space to write the XML file.

view source (Tools menu) was changed to open any plain text file. One benefit is to enable malformed XML files to be quickly opened and inspected.

Fixed a bug in the Xpath dialog that did not list the default namespace unless the XML file had been opened for the first time in XMLMax.

Fixed a bug in the File Save As process to no longer prevent the user from saving a file under a different name if the file had been modified.

Fixed a bug that prevented an element from collapsing if its name includes a namespace prefix and it has a large number (at least several thousand) of child nodes.
