How can I get some data from the tag of a xml file?

I have a tag like this:

```
`<link href="http://127.0.0.1:8580/directory/playlists/" rel="alternate" type="application/atom+xml;type=feed" />`

```

I would like to save the http link: <http://127.0.0.1:8580/directory/playlists/>

Can I use the NSXMLParser?

Thanks a lot!
