How to replace a nodes pcdata or text using pugixml - c++

Question

I am looking for an elegant solution to replacing a nodes pcdata using pugixml (version 1.6). For example, iterating through a node set and updating the child value to something.
pugi::xpath_node_set nodes = document.select_nodes("//a");
for (auto it = nodes.begin(); it != nodes.end(); it++)
{
std::cout << "before : " << it->node().child_value() << std::endl;
// SOME REPLACE GOES HERE
std::cout << "after : " << it->node().child_value() << std::endl;
}
I have used the:
it->node().append_child(pugi::node_pcdata).set_value("foo");
but as the name suggests it just appends the data but I can't find any functions along the lines of:
it->node().remove_child(pugi::node_pcdata);
Another note is that the attributes on the node are important and should remain unchanged.
Thanks for your help.

xml_text object is made for this purpose (among others):
std::cout << "before : " << it->node().child_value() << std::endl;
it->node().text().set("contents");
std::cout << "after : " << it->node().child_value() << std::endl;
Note that you can also use text() instead of child_value(), e.g.:
xml_text text = it->node().text();
std::cout << "before : " << text.get() << std::endl;
text.set("contents");
std::cout << "after : " << text.get() << std::endl;
