Find and Replace pattern that includes a variable string of text

[Ralph Hawkins]

Greetings all.  First time post.  

I need to find and replace a consistent block of HTML that wraps around a variable string of text, like this:

XXXXXXXXXX

adiuhkjashfutrhat

XXXXXXXXXX

and

XXXXXXXXXX

hjsutqpds

XXXXXXXXXX

etc.

I need to replace XXXXXXXXXX with YYYYYYYYY

resulting in this 

YYYYYYYYYY

adiuhkjashfutrhat

YYYYYYYYYY

and

YYYYYYYYYY

hjsutqpds

YYYYYYYYYY

Is there a GREP term or switch that will grab a string of VARIABLE text and carry it over to a replace across dozens of instances?

Thanks all.

Hi Ralph,

Find:

(?s)XXXXXXXXXX(.+?)XXXXXXXXXX

Replace:

YYYYYYYYY\1YYYYYYYYY

Some explanation:

(?s) means allow the dot (which is the regular expression wildcard character) to match at new lines.

(.+?) means capture one or more characters non-greedily.

\1 is the result of that capture.

For anything touching regular expression patterns you should check the excellent BBEdit's menu Help >  BBEdit Help > Grep Reference.

HTH,
