Then why use it repeatedly in a loop, with a string constant? Replace each
use of the X macro where the string is a constant with a variable and put
the variable outside of the loop:
const XStr strServiceProfile("ServiceProfile");
...
for (i=0; i<MAX_NUM_SERVICE_PROFILE_PER_IMPI ; i++){
DOMElement* ServProElem =
doc->createElement(strServiceProfile.unicodeForm());
...
The next step, if that doesn't increase performance enough, would be to
replace XStr completely, as it's not a terribly efficient way to transcode,
especially if you have lots of small strings. Look at the overload(s) of
XMLString that take a buffer for transcoding, instead of returning a newly
allocated buffer each time.
