If you are not very familiar with regular expressions in any language then if you reply with a few examples of what you want to match I can probably help out.
Thank you for your help and prompt reply! Quite familiar, actually - now I managed to work it out. I think mkgmap strips trailing and heading ws from the field content. I stumbled over some of my data having more than two postcomma zeroes (only saw that later, I have a good 1000 files). After some fiddling about I concluded that the whole field content has to be consumed by the RE for a match to occur. So eventually I ended up with this segment in my lines file which now seems to do the job: # only major lines receive a name. Note the conversion to feet. ENT_LIN=2.08.01 & ( QUOTA ~ '.*[05]00\.0+' ) { name '${QUOTA|conv:m=>ft}' } [0x22 level 2] ENT_LIN=2.08.01 & ( QUOTA ~ '.*[05]0\.0+' ) { name '${QUOTA|conv:m=>ft}' } [0x21 level 1] # any remaining contours will be rendered as minor, without name ENT_LIN=2.08.01 [0x20 level 0] the escaped points work as expected. I noticed the example in the wiki was using '\d', so apparently there's shortcuts available (I assume \d is digits - any others?) One more thing: I tried to match a RE at the top level and failed. Is there a workaround to achieve the same thing? My classification is mainly by codes like the ENT_LIN above, and they come in sections. So it would be nice if I could match '2\.08\.??' at the top level. Kay
