I'm having to deal with searching through text containing thousands of
lines for matches.
The text is tab delimited, where one field contains the wrong word and
the second contains the right word. I'm using it as the dictionary for
search and replace.
The text looks like that:
"GM General Motors
Macdonalds McDonalds
MicroSoft Microsoft
etc..."
I know Satimage has some regular expressions to handle such a thing.
Would anyone (Emmanuel) have some code that will return the line that
contains a match at the start of the line. Example:
Search string: "Macdonalds"
Result is the line:
"Macdonalds McDonalds"
Since it starts with the search string.
Using Satimage, this will return a list of all such matching lines:
find text "^macdonalds.*" in (choose file) with regexp, string result
and all occurrences
Each line, by default, is considered a separate record, and the pattern
will try to match within that. The caret (^) matches the beginning of
the record, the dot (.)[1] matches any character, and the star (*) tell
the dot to keep on matching until the end of the record.
'string result' is Satimage's way of saying that you want the actual
text rather than match positions within the text, and 'all occurrences'
ensures that we get each matching record (line) rather than just the
first match.
