| Hint: You need to Download and install "Replace Pioneer" on windows platform to finish following steps. |
| 1. ctrl-o open source text html file 2. ctrl-h open replace window * set "Replace with Pattern" entry to: You can add more replace function outside depending on the maximum nest level. * click "Advanced" Page, fill "Run following at the beginning of Replace" to: 3. click "Replace", done! Note: you can also only follow example of http://www.mind-pioneer.com/services/510_Regular_expression_replace.html But in "Replace window", change the "out page" to the same as "in page", so after the first time replace, you can double click the execution records to execute the same scripts multiple times, to remove the nested tags. |
