parsing of big files

[Nedelcho Stanev <ns...@syntrex.com>]

Hello all,

may be any can help me with this situation
i must parse very big xml file with xerces.
the xml is something like
<element attr1=xx...?
  <tag1>
    data
  <tag2>
</element>
..
..
<element>
 <data>
  ....
  very large data block
  </data>
</element>

so, i want to get this large block on portions
and my question is 
can i do parsing until a go to big chunk
after this simply read data 
and continue parsing from </data> to the end of xml , or to the next portion of data.
i see methods parseFirst/Next in Sax , but really don't have idea
how to do this

You may find more information about progressive parse from http://xml.apache.org/xerces-c/pparse.html and http://xml.apache.org/xerces-c/migrate_archive.html#Progressive.

Please also refer to our sample PParse (samples/pparse/pparse.cpp)

Thanks!
