Hi

I have a TEXT file with unstructured data

-------------------------------------------------------------------********-------------------------------------------------------
ADD UCELLMEAS:CELLID=29335, LOGICRNCID=900, INTERFREQINTERRATMEASIND=INTER_FREQ_AND_INTER_RAT, RPTIND=NO_REPORT, MAXNUMRPTCELLS=CURRENT_CELL_AND_2BEST_NEIGHBOUR, FACHMEASIND=INTER_FREQ_AND_INTER_RAT, FACHMEASOCCACYCLELENCOEF=6, RPTINDIND=REQUIRE, MAXNUMRPTCELLSIND=REQUIRE, INTRAFREQMEASIND=REQUIRE, DEFERMCREADIND=FALSE;
ADD UCELLMEAS:CELLID=29336, LOGICRNCID=900, INTERFREQINTERRATMEASIND=INTER_FREQ_AND_INTER_RAT, RPTIND=NO_REPORT, MAXNUMRPTCELLS=CURRENT_CELL_AND_2BEST_NEIGHBOUR, FACHMEASIND=INTER_FREQ_AND_INTER_RAT, FACHMEASOCCACYCLELENCOEF=6, RPTINDIND=REQUIRE, MAXNUMRPTCELLSIND=REQUIRE, INTRAFREQMEASIND=REQUIRE, DEFERMCREADIND=FALSE;
ADD UCHPWROFFSET:CELLID=21711, LOGICRNCID=900, AICHPOWEROFFSET=-6, PICHPOWEROFFSET=-7;
ADD UCHPWROFFSET:CELLID=34051, LOGICRNCID=900, AICHPOWEROFFSET=-6, PICHPOWEROFFSET=-7;
ADD UCHPWROFFSET:CELLID=34052, LOGICRNCID=900, AICHPOWEROFFSET=-6, PICHPOWEROFFSET=-7;
ADD UCHPWROFFSET:CELLID=34053, LOGICRNCID=900, AICHPOWEROFFSET=-6, PICHPOWEROFFSET=-7;
-------------------------------------------------------------------********-------------------------------------------------------

I am only interested in extracting rows that contain "UCHPWROFFSET" and would like to convert it to the below format (Tabular)

CELLID  LOGICRNCID  AICHPOWEROFFSET  PICHPOWEROFFSET
21711          900                    -6                              -7
34051          900                    -6                              -7
34052          900                    -6                              -7
34053          900                    -6                              -7


Any idea how it can be done using Operators within RAPIDMINER

    A regular expression using Cut Document would do the trick. 
    I haven't the time to create the exact ones you need, but the basics would be a lookbehind for each field for example
    (?<=.*UCHPWROFFSET.*CELLID\=)[0-9]*  (or something like that)

    For ease of demonstration here is a quick demo I knocked up, I doubt you'd want to use this in production though and will need to tweak it a bit.
