Hello,

 

concerning Boost.PropertyTree:

 

First:

Taking the example file from the Tutorial:

<debug>

    <filename>debug.log</filename>

    <modules>

        <module>Finance</module>

        <module>Admin</module>

        <module>HR</module>

    </modules>

    <level>2</level>

</debug>

 

The module entries are parsed using

    BOOST_FOREACH(ptree::value_type &v,

            pt.get_child("debug.modules"))

        m_modules.insert(v.second.data());

 

But reading the documentation for "get_child" confuses me:

 

---------------

self_type & get_child(const path_type & path);

 

Get the child at the given path, or throw ptree_bad_path.

 

Notes:

Depending on the path, the result at each level may not be completely determinate, i.e. if the same key appears multiple times, which child is chosen is not specified.

[...]

---------------

 

So how is it garantueed that BOOST_FOREACH will iterate over all the children?

 

 

Second: (This is my actual problem)

If for example i extend the file a bit like this:

<debug>

    <filename>debug.log</filename>

    <modules>

        <module>Finance</module>

            <param1>100</param1>

            <param2>200</param2>

        <module>Admin</module>

            <param1>100</param1>

            <param2>200</param2>

        <module>HR</module>

            <param1>100</param1>

            <param2>200</param2>

    </modules>

    <level>2</level>

</debug>

 

Now the "modules" have sub-items.

How would i go to iterate over the modules and children if i'd need to create an object for each module and associate the right params to each?

 

Thanks,

regards,

Lars
