XMLCh* string comparison

[Mark]

I've just started using Xerces and I'm using SAX2XMLReader to parse a ~250MB xml 
file. In the startElement function of my content handler I need to compare 
localname e.g. if (localname == "something"). I know I can't use == but I can't 
figure out what to use. Can anyone point me in the right direction?

TIA
