This is the desired outcome for a sample input (D1 below)
However the output I am getting is below D2.
The parent filter is working perfectly.
The child filter is invoked on the 3 occasions when the SEARCH_STRING is found in the parent filter output. This corresponds to paragraphs 5, 7 and 8.
However on these 3 occasions the entrire paragraph is not extracted.
The screenshot D3 below shows the parent filter having correctly identified paragraph 4. The parent filter behaves in this way for all paragraphs. In the case of non interesting paragraphs (1,2,3,4,6 and 9) the child filter is never shown in this fantastic "Prompt on replace" feature. I wish I had know about this years ago.
The screenshot D4 below shows the parent filter finding paragraph 5. This is the first interesting paragraph (i.e. one for which an output is desired as this contains the target SEARCH_STRING)
Because the replacement text in the parent filter execution (Marker 2 in D4 above) has a non empty output for the child filter, the next screen shows the action of the child filter for the first time (D5 below). The found text (marker 3 in D5 below) is the accurate output of the parent filter (marker 2 D4 above). This is the text being fed into the child filter as I would understand. The child filter search string (Marker 5 D5 below) as you can see is
I would expect that this regex search string to find the entire text. Instread it replaces the found text with text truncated at the end of the target SEARCH_STRING as you can see.
Code: Select all
Note that for both parent and child filters the Perl matching options are
- Non greedy shortest default match; and
- "." matches new line
Parent filter, which seems to work perfectly is shown in D6 below:
The child filter, which seems to be matching unexpectedly, is shown in D7 below
What am I doing wrong with the child filter?
Very grateful for any help in this matter
