strange characters in attribute val

[GoogleCodeExporter]

What steps will reproduce the problem?

I'm parsing an xml file and retrieving a value from it using an xpath 
expression:
std::string val = doc.select_single_node("xpath 
expression").node().child_value();

and then rewriting it as an attribute in a new xml document:

newxml.append_attribute(val.c_str());

What is the expected output? What do you see instead?

value of val expected (1,8361); Val printed out using std::cout
Instead I get "
1,8361" in the newxml file attribute

Which version of pugixml are you using? On what operating system/compiler?

Using g++ with pugixml 1.2

Please provide any additional information below.

This character is an XML encoding of a newline (\n).
It is there because pugixml treats PCDATA whitespace as significant; to fix 
this you'll have to trim the string that you get from child_value.

There used to be a parsing option that did this for all PCDATA elements; it may 
be reimplemented again in the future, but for now manual trimming is the only 
solution.

Hi,

I've tried trimming the string but I can't seem to delete the chars.

Using:
val.erase(0,5) results in deleting the actual data I want. It seems that the 
data exists within the string (as revealed by std::cout) but cannot be accessed 
in the string.
