currently i have many html pages which i need to extract 2 pieces of information. The current expression i am using allows me to extract one information, what if i need to extract 2 pieces of data at the same time.
(?s)\A.*(var vpart=".*?";var pn).*\Z replace $1
This is the expression i am using, i need to extract another data in the < title > tags, can some one help me to amend the above expression?
Yes, use more groups:
(?s)\A.*(var vpart=".*?";var pn).*(var endpart=".*?";var mn).*\Z
See proof.
Replace with: $1\n$2
With more groups, add more \n$X.
Explanation
--------------------------------------------------------------------------------
(?s) set flags for this block (with . matching
\n) (case-sensitive) (with ^ and $
matching normally) (matching whitespace
and # normally)
--------------------------------------------------------------------------------
\A the beginning of the string
--------------------------------------------------------------------------------
.* any character (0 or more times (matching
the most amount possible))
--------------------------------------------------------------------------------
( group and capture to \1:
--------------------------------------------------------------------------------
var vpart=" 'var vpart="'
--------------------------------------------------------------------------------
.*? any character (0 or more times (matching
the least amount possible))
--------------------------------------------------------------------------------
";var pn '";var pn'
--------------------------------------------------------------------------------
) end of \1
--------------------------------------------------------------------------------
.* any character (0 or more times (matching
the most amount possible))
--------------------------------------------------------------------------------
( group and capture to \2:
--------------------------------------------------------------------------------
var endpart=" 'var endpart="'
--------------------------------------------------------------------------------
.*? any character (0 or more times (matching
the least amount possible))
--------------------------------------------------------------------------------
";var mn '";var mn'
--------------------------------------------------------------------------------
) end of \2
--------------------------------------------------------------------------------
.* any character (0 or more times (matching
the most amount possible))
--------------------------------------------------------------------------------
\Z before an optional \n, and the end of the
string
