Finding lines with different words between tags

[greg123]

Hi,

In a large txt file I'm unsuccessfully trying to find lines, that contain different words between tags <tag1></tag1> and <tag2></tag2>.

Example:

<tag1>abc</tag1><tag2>abc</tag2>
<tag1>def</tag1><tag2>def</tag2>
<tag1>xxx</tag1><tag2>ccc</tag2>

In this example only <tag1>xxx</tag1><tag2>ccc</tag2> line should be matched. Please help.

Best regards,
Greg

What about searching with Perl regular expression engine for <tag1>(.*)</tag1><tag2>\1</tag2> with using button Hide Lines. That hides all lines containing the same string between both tags and the remaining lines are those with different strings between the two tags.

I can't believe it's so simple.
Thanks a lot!!!

Another way would be to search for

Code: Select all

<tag1>(.*?)</tag1><tag2>(?!\1).*</tag2>

This matches pairs of tag1/tag2 tags that don't have the same content.
