问题描述:

I'm using boost 1.51 and have something like this:

boost::property_tree::ptree some_tree;

some_tree.put("hello.world.<xmlattr>.foo.bar","4711");

I was hoping to get

<hello>

<world foo.bar="4711"/>

</hello>

But I only get

<hello>

<world foo=""/>

</hello>

Using boost::property_tree, is it possible to create an xml file with an attribute name containing a '.' character or do I need to look elsewhere?

网友答案:

You have to use a separator other than the default .. Try this,

boost::property_tree::ptree some_tree;
some_tree.put(ptree::path("hello/world/<xmlattr>/foo.bar", '/'),"4711");
