Search and Replace EVERY 2nd occurrence i.e. alternate occurrences

Submitted by highab on Thursday, 3 February, 2011 - 10:45

Hi, I'd like to be able to search and replace paragraph marks (\n) with tab marks (\t) for every other line down to the end of a document, effectively merging two lines into one with a tab in between.

thus turning

term1
term2
something else 1
something else 2

into

term1[tab]term2
something else 1[tab]something else 2

this is the code I have so far

SearchAndReplace.setSearchString("\\n");
SearchAndReplace.setReplaceString("\\t");
SearchAndReplace.setBeanShellReplace(false);
SearchAndReplace.setIgnoreCase(true);
SearchAndReplace.setRegexp(true);
SearchAndReplace.replace(view);
SearchAndReplace.setSearchString("\\n");
SearchAndReplace.setBeanShellReplace(false);
SearchAndReplace.setIgnoreCase(true);
SearchAndReplace.setRegexp(true);
SearchAndReplace.find(view);

but if I put it into a loop for textarea number of lines, it replaces ALL occurrences of \n and not every other one.... I'm stumped.

Anyone have any ideas please?

Hi,
the replace() method doesn't do anything unless some text has been found before. So, Your first loop only find an occurrence and the second loop replaces it and finds the next one...

Try this:
SearchAndReplace.setSearchString("\\n");
SearchAndReplace.setReplaceString("\\t");
SearchAndReplace.setBeanShellReplace(false);
SearchAndReplace.setIgnoreCase(true);
SearchAndReplace.setRegexp(true);
SearchAndReplace.find(view);
SearchAndReplace.find(view);
SearchAndReplace.replace(view);

I'd tried all sorts of things like that actually... in longhand, so its nice to see that the shorthand way IS possible.

The missing bit was

SearchAndReplace.setAutoWrapAround(false);

probably due to my loop grammar not being great, but hey, I've got it working now... Thanks!
