Hello,
I am extracting lines from a text file with the regex task. I'm finding that if
the source file is 50k or so, the search takes 10-15 seconds. The performance
is dramatically worse if the input is bigger, becoming 5+ minutes by the time
the file is 100k. Anyone else seen this?
I don't use regex much, so I'm hoping I'm doing something inefficiently. The
code is below. Any help is appreciated.
<loadfile file="${inputfilename}" property="fileContent"
verbose="false"/>
<regex
pattern="^[\s\S]*${startstring2}(?'matchedLines'[\s\S]*)[\s\S]*${endstring2}"
input="${fileContent}"/>
<echo message="${matchedLines}" file="${outputfilename}" append="true"/>
THX
Curt
