https://community.intel.com/t5/Intel-Integrated-Performance/How-to-replace-ALL-matched-sub-strings-with-RegExpReplace/m-p/807424#M3703 Hi,<BR />There is 'const char* pOptions' parameter in the function ippsRegExpInitAlloc. You can change search strategy by passing combination of 'i', 's', 'm', 'x', 'g' characters. By default first matched substring will be replaced. Please set in to the 'g'. 'g'is global search. That means all matched substrings will be replaced.<BR /><BR />Igor S.

Following is an example.<BR /><BR />regex: [BD]<BR />src string: ABCDE<BR />replacement: ##<BR />wanted dist string: A##C##E<BR />actual dist string: A##<BR /><BR />How to write regex and replacement to get my wanted dist string? Or IPP just doesn't support that?<BR /><BR />What's more, even IPP only supports replacing the first occurrence of the matched sub strings, I would expect the dist string to be "A##CDE"...<BR /><BR />Thanks,<BR />-Evan Wed, 13 Oct 2010 10:13:56 GMT https://community.intel.com/t5/Intel-Integrated-Performance/How-to-replace-ALL-matched-sub-strings-with-RegExpReplace/m-p/807423#M3702 evanyan 2010-10-13T10:13:56Z https://community.intel.com/t5/Intel-Integrated-Performance/How-to-replace-ALL-matched-sub-strings-with-RegExpReplace/m-p/807424#M3703 Hi,<BR />There is 'const char* pOptions' parameter in the function ippsRegExpInitAlloc.
