    XML parsing with C++

    I am trying to parse an xml document and extract certain information, I am new to all this so sorry if i come across as a reall newb.

    My file would have multiple contacts in the file. I am trying to extract and output only certain bits of contact info depending on what postcode, county, city etc they live in. I want the code to be usable in C++ format.

    What would be the best way to do this and is there a tool that will do it for me?

    thanks in advance for reading.

    Are you open to using a library to do all the grunt work?

    Xerces-C++ XML Parser
    or
    The Expat XML Parser
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    boost::property_tree is a lightweight solution to this, it doesn't have anywhere near the features of a dedicated xml-parser but it's extremely easy to use.

    hi jachstws7, dont worry about it, i am fairly new to c++ as well, however I have started using tinyxml++ and liquid xml c++, both of which are pretty good but if you want lightweight, tiny is the better choice.

    I also suggest Liquid XML. It is good for C++ code base and has rich functions placed in. MSXML also a good one, but I don't know why people hate it.

    Are you frakkin' kidding me?? MSXML becomes somewhat bearable only once you've built a wrapper around it that totally hides the fact that MSXML is somewhere underneath it.

    That's larely due to using a C interface from C++, which can be the case with any API.
    MSXML itself is actually very good and I would also recommend it.

    Xerces is a fine piece of software as long as you do not look at the output it creates. Some of those files are uber nasty. But what Xerces can do is amazing and is akin to the XML support available in .NET.

    I've had good experiences with pugixml recently. It's a new library, but seems stable, and it has a more modern C++ style than many others. But Tinyxml is okay too, and definitely more widely used.

    I used expat once and it was really complicated, minixml was way simpler -- this was in C though, not C++. Still, you may want to go for somewhat smaller/simpler libraries to start with. As you can tell, there are a lot of XML libraries out there! Here's a list if you're curious. Free C/C++ XML Parser Libraries
