Hai,

Thank you for considering me, let me tell you straight, There are two file a.txt and b.txt, i want each line of text in a.txt should be searched, if searched text found in b.txt then it has to replace with a newline along with the searched text, i hope so this will be clear to you.

The code which you gave for replace is working only if the text come in between the open tag and closed tag,

For example

<! This is the sample text > -- For this the search is working fine.

<! This is the <i>sample</i> text > -- For this the search is working till the italic closing tag not the actual closing tag.

Regards,
