extract from html

[Lydia Shawn]

hi,
how can i extract the number between text1 and text2 in input.html
only the first time it occurs ignoring the rest?
preferably input.html would be a URL that stops downloading once a
match has occured, that would save a lot of bandwidth..
i guess html::parser would provide an option to work with a file while
it's downloading (?)

example
----

input.html:

bla..
text1 555 text2
bla
bla
text1 6000 text2
bla
EOF
output.txt
555
thanks for your help,
peter

This problem I would solve by using a Hash. You can just put a unique key
into it, while finding the same term
it will be overwritten, or you can ask the hash if the term already exist

# $term is taken from your text - inbeetween text1 / text2
if( exists $myHash{$term})
{
# ignore
}else
{
$myHash{$term} = $value;
}

The Rest of your question : I don´t know ... sorry
thanks for your help,

Take a look at the lwp-download script (in your perl bin directory)
as an example of a program that incrementally downloads a URL.
You can then search the contents for your text1 and text2 and stop if found.

The script uses LWP::UserAgent to do the download.
