Re: [Boost-users] Editable XML Serialization

Hi,

Dear list members,

I guess it's one of the hardest search terms around but I would like to know if there is any editable XML serialization provided by Boost or other C++ libraries. And I don't mean the kind of thing that requires you to go jumping around through trees, with iterators etc. I don't want to see any iterator!

...

lit("</data1>") >> lit("<data2>") >> int_ >> lit("</data2>") >>

I thought of something like this too. Actually, a specific XML-Format could easily be implemented using boost.spirit: qi::rule = lit("<xml>") >> lit("<data1>") >> double_ lit("</xml>"); This way, you could define your own XML-based-grammar which then gets parsed into structs. Thats enough for most applications IMO. But this syntax is ugly, by writing own spirit-parsers, the syntax might look like this: qi::rule = node("xml") [ node("data1") [double_] >> node("data2") [double_] ]; Spirit will also complain if the format is unexpected, and throw an exception containing an iterator pointing to the faulty position. Is this enough for you? (You might want to take a look at spirit, to understand what's going on here)

It would be so great if there is something like this in which the XML files can actually be edited! I am almost sure that there should be something like that, but I can't find it.

You can edit the file by using a karma-rule that works exactly like the qi::rule, but is used for output instead. Spirit is very fast, probably faster than editing the XML and saving it using another xml-library. Regards, michi7x7
