Java Extract expressions between two strings in html file
Hello guys,

I'm trying to extract all the expressions between the following tags: <b></b> from a HTML file.
This is how it looks: big lines containing several dozens expressions (made of 1,2,3,4,6 or even 7 words) I would like to extract:



Code:
<b>bla ble</b>bla ble</td><tr valign="top"><td width="50%"><p align="left" style="margin-top:0;margin-bottom:0"><b>ble bla ble</b>bla bla ble</td><td width="50%"><p align="left" style="margin-top:0;margin-bottom:0"><b>ble ble ble bla ble</b>ble ble ble bla ble</td><td width="50%"><p align="left" style="margin-top:0;margin-bottom:0"> and so on.

I would like to print them out into a new file, under the form:

bla ble
bla bla ble
ble ble ble bla ble

etc.

I know several posts in the forum adress this question - namely to extract expressions between two strings using sed, perl or awk - but none of the commands I found work in this situation (several of the same tags on the same line and a lot of lines).

How could I make either one of these programs go through the WHOLE file in search of every expression that appear between <b></b>?


Thank you very much !

This extract the data that is between the "b" tags:
Code:
$ cat test.txt | sed -e 's/<\/b>/<\/b>\n/g' | sed -n -e 's/.*<b>\(.*\)<\/b>.*/\1/p'
bla ble
ble bla ble
ble ble ble bla ble
