For example when filtering html file, if every line is in this kind of pattern:
<a href="xxxxxx" style="xxxx"><i>some text</i></a>
how can I get the content of href, and how can I get the text between <i> and </i>?

@Ignacio Vazquez-Abrams: Does xmlstarlet work with HTML too?Gumbo– Gumbo2010-12-21 05:32:27 +00:00Commented Dec 21, 2010 at 5:32

@Gumbo: You'd have to shove it through HTML Tidy first, but that's not too big a deal. And it's more a matter of the option not existing, not the underlying libraries being unable to handle it.Ignacio Vazquez-Abrams– Ignacio Vazquez-Abrams2010-12-21 05:33:31 +00:00Commented Dec 21, 2010 at 5:33

cat file | cut -f2 -d\"
FYI: Just about every other HTML/regexp post on Stackoverflow explains why getting values from HTML using anything other than HTML parsing is a bad idea. You may want to read some of those. This one for example.

If href is always the second token separated by space in a,ine then u can try
grep "href" file | cut -d' ' -f2 | cut -d'=' -f2

Here's how to do it using xmlstarlet (optionally with tidy):
# extract content of href and <i>...</i>
echo '<a href="xxxxxx" style="xxxx"><i>some text</i></a>' |
xmlstarlet sel -T -t -m "//a" -v @href -n -v i -n
# using tidy & xmlstarlet
echo '<a href="xxxxxx" style="xxxx"><i>some text</i></a>' |
tidy -q -c -wrap 0 -numeric -asxml -utf8 --merge-divs yes --merge-spans yes 2>/dev/null |
xmlstarlet sel -N x="http://www.w3.org/1999/xhtml" -T -t -m "//x:a" -v @href -n -v . -n
