Vista - ANN: XMLMax Beta Adds Indexing For Faster Xpath Query

March 30, 2009

Xponent is pleased to announce Beta version 2.0.6 of its XMLMax
Virtual XML Editor. This version introduces two features, indexing
for faster xpath queries, and instant re-loading of xml documents of
any size(tested to 10Gb).

Beta testers who work with xml documents, preferably with files
several megabytes to several gigabytes in size, are needed at this
time.

What does XMLMax do?

XMLMax provides editing, xpath query, xsl transformation, validation
and well-formed checking of any size xml file.

XMLMax needs only 600 megabytes of free memory for even the largest
xml file.

****** Key Features: ******

* Incremental parsing and loading.

* A 75Mb file is fully parsed and loaded in three seconds, a 250 Mb
file in sixteen seconds. Parse and load rate is linear at about 1Gb/
minute and has been tested with files over 10Gb.

*When an xml file is first parsed, a small stub file is created that
enables the file to be-reloaded instantly the next time is is opened,
provided it has not been modified.

* Xpath queries are limited to forward-looking xpath expressions.

* Reads and writes UTF-8, UTF-16 and iso-8859-1.

* Protected editing. Markup characters in an xml file are never
accessible for editing.

* Detection, location and correction of any well-formed error at load-
time, including files without carriage returns and line feeds.

****** Architecture ******

XMLMax was written in C# with the .Net 2.0 Framework. A proprietary
virtual treeview was developed by Xponent from the ground up and never
contains more elements than those actually visible (child elements not
visible are not in the tree at all). This design provides
instantaneous inserts and deletes at any location, even in the largest
files. There are no third party licenses, controls, or libraries.
