Hi,

This is more a theoretical question, because I usually solved that with perl or even java, but I would like to know if it exists an easy way to do it with SED.

Using regular expresions it's very easy to select an portion line. Does it exist an easy way for printing those portions in SED?

For example, let's suppose that in an HTML file I want to print all links. Selecting the links it's very easy. Just for keeping the things simple, let's suppose the HTML is a well formed one

href=['"]\([^'"]*\)['"]

so \1 holds the link. Now my question, does it exist an easy way in sed for printing all the links?

So, if I have

XXXX href='link1' ZZZ href='link2' XXXX

I want to have

link1
link2

The only way that I know for doing that in sed is deleting everything except the links, but I'm sure it must exist an easier way to do it.

Thanks a lot
