Performance.   XMLMax opens huge xml files in a treeview much faster than any other product. It can load the treeview at 1 GB in five seconds(or even quicker with the fastest hard drives). It does this without a database, indexing, configuration or pre-processing. Re-opening any XML takes under two seconds. Thanks to our proprietary treeview technology there is never an issue with insufficient memory or the treeview becoming unresponsive.

XML Syntax Errors.  An XML editor should detect and report if your XML is not well-formed(violates the XML specification). If it is not, XML compliant software will not be able to 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.  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. Our performance tests show it took twenty-three minutes to fully parse this file and load it into the treeview. A very fast system is recommended for such large files, but only 500 MB available RAM are needed because of XMLMax's file segmenting and buffering.

What's New

Current version: 4.2

The text search feature was entirely re-written to enable more flexibility including the following changes:

  • Interactive searching starts and resumes at the current treeview node.
  • XML content may be edited, including inserting and deleting nodes, before and during a search.
  • Edited content is searched without having to save the file.
  • A new search may be started without having to save the file.This enables using the text replace feature and then searching again to verify the replacements before saving the file.
  • Internal bookmarks for all hits in the search results list are updated when edits are made so the Go-to feature is accurate.
  • New search options include ignoring XML tag names and XML attributes.
  • When search is cancelled, any matches found prior to cancelling appear in the results list.

Validation has additional flexibility:

  • XML content may be edited, including inserting and deleting nodes, without impacting the Go-to feature in the results list.

XPath Query has the following changes:

  • The format of the List output includes the entire OuterXml content up to user-specified maximum length.
  • The Treeview output is much faster. The XPath query continues to use an XPathNavigator wrapped by an XPathDocument, but a new design was implemented for mapping the resulting nodeset items to the treeview.
  • For the treeview output, XML content may be edited, including inserting and deleting nodes, without impacting the Go-to feature in the results list.

System Requirements

Any non-mobile Windows Operating System From XP to the most recent.
One gigabyte of random access memory is recommended.
