Class XMLProfiler

java.lang.Object
org.apache.tika.parser.xml.XMLProfiler
All Implemented Interfaces:
Serializable, Parser

public class XMLProfiler extends Object implements Parser

This parser enables profiling of XML. It captures the root entity as well as entity uris/namespaces and entity local names in parallel arrays.

This parser is not part of the default set of parsers and must be "turned on" via a tika config:

<properties> <parsers> <parser class="org.apache.tika.parser.DefaultParser"/> <parser class="org.apache.tika.parser.xml.XMLProfiler"/> </parsers> </properties>

This was initially designed to profile xmp and xfa in PDFs. Further work would need to be done to extract other types of xml and/or xmp in other file formats. Please open a ticket.

      public void parse(InputStream stream, ContentHandler handler, Metadata metadata, ParseContext context) throws IOException, SAXException, TikaException
      Description copied from interface: Parser
      Parses a document stream into a sequence of XHTML SAX events. Fills in related document metadata in the given metadata object.

      The given document stream is consumed but not closed by this method. The responsibility to close the stream remains on the caller.

      Information about the parsing context can be passed in the context parameter. See the parser implementations for the kinds of context information they expect.

      Specified by:
      parse in interface Parser
      Parameters:
      stream - the document stream (input)
      handler - handler for the XHTML SAX events (output)
      metadata - document metadata (input and output)
      context - parse context
      Throws:
      IOException - if the document stream could not be read
      SAXException - if the SAX events could not be processed
      TikaException - if the document could not be parsed
