How to match the regexp globally in a file

Question

I am having a file say text.txt having similar blocks of patterns like

<tr> I am nitesh goyal <\tr> nothing nothing <tr> I logged in stackoverflow<\tr> nothing nothing <tr> I want help to solve this <\tr> anyhting anything.

I want to take all the blocks data<\tr>.

currently i am using the regexp

I stored the file in a variable buffer
regexp "tr.*?\\tr" $buffer

But it is giving only fist block. How to take all the blocks present with the same delimiter.

Is it possible to have one block at a time and do some operations and then take second and so on.

Is that an attempt at HTML? Your tags aren't matched and `\\` does not belong in the terminating tag. — Marc, May 04 '12 at 14:22
yes i am attempting to do some operations on html file. i stored the file in a variable and want to do some operations on particular blocks — Sumit, May 04 '12 at 14:27

Use -all -inline options. In this case regexp command will return the list of all blocks it found.

set list_of_found_blocks [regexp -all -inline -- "tr.*?\\t" $buffer]

@Nitesh, the variable `list_of_found_blocks` is a list, so you can just iterate over it using `foreach` – glenn jackman May 04 '12 at 15:05
