Extracting a data from a string

[Dan]

Good morning/evening,

Having a string like

<img src="http://mywebsite_address/mypath/-picture.gif"></a><br>


How can I extract "-picture.gif" from this string ?

The name will, for example, always begin by "-"
It will be for example -pic1gif, or -pic8.gif, etc.

Thank you,

Dan

In Perl, it can be done with a regular expression.

:The name will, for example, always begin by "-"
:It will be for example -pic1gif, or -pic8.gif, etc.

And will it *always* be on one line? No possibility of it having
been split by printable-quoted into something such as

<img src="http://mywebsite_address/mypath/-pict=
ure.gif"></a><br>

??

And is it certain that there will be the closing double-quote? The
HTML spec does not strictly require that all strings be double-quoted,
only strings that have certain characters in them.

What are the valid characters in the name?

my ($fid) = $string =~ /(-[a-zA-Z0-9.]+)"/

But this wouldn't match names that included imbedded dashes or
underscores or characters such as & or blanks -- you have failed to
give us a specification of what *is* allowed in the filenames.

No, always one line as described above, with the double-quotes

Better even, all before the sign "-" will be always the same. The only
variable is the name of the gif file itself.

The pics will *always* be nammed -picturexxxxx.gif
where xxxx are digits, and only.
