[xml] Error in the Tutorial

[m masson t-online de (Michael Masson)]

Hallo

At the Tutorial for libxml2 is a error in the source code.  The error is in 
the XPath example on Line 35. See the compiler message

xpath_example.c: In function `int main(int, char**)':
xpath_example.c:35: error: invalid conversion from `const char*' to `xmlChar*

the line lock 

xmlChar *xpath = ("//keyword");

but it must lock

xmlChar *xpath = xmlCharStrdup("//keyword");


best regards
