XML Cleaner - Filter and Validate XML Files

XML Cleaner is a command line utility to filter and validate XML files.

XML Cleaner is written in Ada 9X and so it is rather fast.

Download: XML Cleaner 0.2.2beta source (Licensed under GPL); you need also XMLAda with patches to compile it.

Features:

• removes superfluous namespace declarations;
• choice of several forms of empty tags;
• XML validation (against the DTD);
• Unicode support;
• removal of comments;
• removal of ignorable whitespace;
• options to set output of XML declaration and standalone declaration;
• options to output or not output <!DOCTYPE> declaration;
• options to escape or not escape quotes and apostrophes;
• options to use single or double quotes in arguments;
• (More to implement: XML canonicalization, reformatting, XML charset recoding, XInclude processing, inplace file modification, etc.; XML Cleaner is to grow into a full featured command line XML filter and validator.)

I have written this program because xmllint from libxml2 does not support removal of unused namespaces (it only removed duplicate namespace declarations, what is not enough).

It is particularly important because many programs generate XML files with superfluous namespaces, and these files do not validate against DTDs such as XHTML DTD.

XML Cleaner is developed to become xmllint replacement.

Please send patches.

The immediate purpose why XML Cleaner was developed was to process math articles in XML format for www.mathematics21.org Web site.
