Hi, I am trying to finish my review of the Property Tree. I find the scope of the library for program configuration very useful. I am currently testing only the read_xml parsing, and although it is only meant for very simple xml files i find its xml support very very sketchy. I've performed multiple experiments with rss feed files, which are very simple xml files. This is the loop I am using to test different xml paths using a command line utility: BOOST_FOREACH(ptree::value_type &v, pt.get_child( argv[2] )) cout << "value: " << v.second.data() << endl; Below is a list of my experiments: 1. parsing the artima.com spotlight feed Result: FAILED The path is rdf:RDF.item.title and I get invalid character entitly. I think the parser should support the semicolon within the tag name, given that in many cases the config files might be generated by real xml programs which use namespaces and it should be able to read them even if it does not support save. 2. parsing the MSDN visual c++ feed Result: FAILED The path is rss.channel.item.title and I get an "xml parse error". Is there a posibility of getting more meaningful errors ? 3. parsing the main CNN feed Result: FAILED The path is rss.channel.item.title. This query fails with no error but if the path is shortened to rss.channel.item it dumps all the values within item, but there is no value at that level (only nested tags) 4. Parsing the Google News RSS feed Result: FAILED The path is rss.channel.item.title. I get "Invalid character entity error". A more meaningful error should be possible with the position in the file where the entity occurs. 5. Parsing the Google News Atom feed Result: FAILED The path is feed.entry.title. I get "Invalid character entity error". regards jose
