[RfC] XML_Statistics

Hi, I'd like to propose a new package called XML_Statistics. I can be used to obtain a lot of statistical information from XML documents. Currently, it's able to get: * total number of tags in document * number of tags in a specific nesting level (i.e. number recordsets in RDF document) * occurences of a specific tag * total number of attributes in document * occurences of a specific attribute * occurences of a specific attribute in a specific tag * total number of processing instructions * total number of processing instructions for a certain target * total number of external entities * total number of a specific external entity * number of CData chunks * total length of all CData chunks Sourcecode and more can be found at: http://www.php-tools.de/PEAR/XML_Statistics/ Comments welcome.
