dhtmlxGrid XML loading

An error in the XML parsing prevents setting the #cspan or #rspan headers. The regular expression used ‘/^\s*((.|\n).+)\s$/gi, “$1”’ will not remove the new line character for the column name, the expression should be ‘/^\s*((\s\S).+)\s$/gi, “$1”’.

Problem is confirmed.
We will update this part of logic in next build
Thanks for provided solution.
