The "MSOfficeParsers" page has been changed by TimothyAllison: https://wiki.apache.org/tika/MSOfficeParsers?action=diff&rev1=3&rev2=4 = Tika's MSOffice Parsers (Apache POI) = - == Experimental SAX Parser for .docx == + == Experimental SAX Parser for .docx and .pptx == - As of Tika 1.15, there is an experimental SAX parser for .docx files. On very large files (e.g. "War and Peace"), this parser appears to be 4x faster and require far less memory than our traditional DOM based parser. For smaller files, the gain is not nearly as great, but it is still faster. This parser is still in its early stages and doesn't have all of the features of the DOM parser. However, it does offer parameterization to include or exclude deleted text. + As of Tika 1.15, there are experimental SAX parsers for .docx files.
