问题
Okay, so I already have a Pipe where I extracted the string I need from item.description, using the Loop and String Regex modules, and am emitting the results with the "emit results" option. Now, where do I go from here?
EDIT: Since an example was requested, here is one:
The item.title is "NBA Game: Lakers vs. Clippers" and the item.description is "The game went into overtime. The final score was 110-90." So the I'd like to extract "110-90" and copy it to the title, where it would then be "... Clippers (110-90)".
回答1:
1/ Put the score in "scorefield"
Rename operator: [item.description] [COPY AS] [scorefield]
Regex operator : in [scorefield] replace [.*\(([^)]+)\).*] with [$1]
2/ Append score to item.title
Regex operator : in [item.title] replace [($)] with [$1 ${scorefield}]
Nota :
In the above lines the outside square brackets are to be omitted unless noted otherwise
