search for text string in a file

Hi there,

I have a background as a mainframe programmer. Assembler, Cobol etc.

Never looked a C++ before but I have a file that contains HTML source and would like to search the file for a particular text string and then select data following this text string and then output th data to a file.

Can this be easily done in C++. If so, could someone point me in the right direction as to what commands I should look to use.

I await you reply with interest.

You should learn basic C++ first, if you've never looked at C++ before. Why do you want to use C++ for this?

It could be easily done in perl.

It might also be easily done in python, or ruby(?)

Code:

---

$ perl -n -e 'print "$1\n" if ( /match([0-9]+)/ );'

---

The match is whatever uniquely identifies the prefix text
The ([0-9]+) is whatever uniquely identifies the text you want to print

Interactive Example

Code:

---

hello world
match1234
1234
this doesn't match
