Hi Abir,

Now I am looking to use spirit for parsing an specific xml file ( w3c inkml file). So my intension is not to have a generic xml parser, rather than a specific xml parser (which also have some BNF grammar) . Anyone had used spirit for domain specific xml parsing?
Trust me you don't want to go this route. Parsing XML is a lot more than finding opening and closing tags. To implement a conforming XML parser you will need to handle namespaces, entity references, CDATA, etc. This is a lot harder to get right than most people think. The only time it makes sense to have a domain specific XML parser is when you have control over all your XML instances and can make sure that only a subset of XML 1.0 is used. This is normally done for performance reasons.
I believe using spirit will make it faster.
Highly unlikely since most of the XML parsers are hand-coded.
Also I am interested to parse only a portion of the whole document at a time, and generate data from that portion only, rather generating data for whole DOM (The files are large, 4-20 MB typically) my xml file is something like,
[...]
note that inside <trace> the grammar is a BNF (comma sep float pairs mostly)
You can use a SAX2 parser (e.g., Expat or Xerces-C++) to handle XML and then use Spirit-based parser to handle the data. hth, -boris -- Boris Kolpackov Code Synthesis Tools CC http://www.codesynthesis.com Open-Source, Cross-Platform C++ XML Data Binding
