Shell Programming and Scripting

hi,
i have this string:

Code:

<TD CLASS="xxxxxxxx" data-sort-value="xxx999" TITLE="xxxxxxxxxxxx">xxxxxxxxxxxxx</TD>

this string has diffrent value ech time, i want to store just the value of "data-sort-value" in this exemple is xxx999

can someone help me on this

How big is this problem?

Do you have this one exact line to deal with and nothing else, or a load of other XML to manage i.e. picking it specifically out of a file etc?

Pipe it to

Code:

sed -n 's#^.*data-sort-value="\([^"]*\)".*$#\1#p'

If you have the string in a shell variable, then

Code:

echo "$string" | sed ...

can be smart-replaced with

Code:

expr x"$string" : x'.*data-sort-value="\([^"]*\)"'

thank you very much sir that s work,
please can you explain me the code i want to use it on

Code:

<TD CLASS="usercol3">00:12:25<BR></TD>

to extract th time

A possibility for general purposes:

Code:

perl -nle '/(\d+:\d+:\d+)/ and print $1' extra93.file
00:12:25

Or if it needs to be specific to the usercol3 class

Code:

perl -nle '/usercol3">(\d+:\d+:\d+)/ and print $1' extra93.file
00:12:25

A less precise alternative sed version:

Code:

sed -n 's/^.*usercol3">\([^<]*\).*$/\1/p' extra93.file
00:12:25

thank you friend it realy help, but i mean for exemple this

Code:

\([^<]*\)

i want to undestand the fonctioning of the code but thank you one more time

If you want to know more, search for regular expression character classes or character set and negated character class

Some characters inside a square bracket means, means match one time either of those characters.
[abc] match either an a or a b or a c one time
[abc]* with an * will match many times
[^abc] with an ^ in front, will match any character that is NOT an a or a b or a c one time.
[^abc]* with an * means, keep matching anything as long as it is NOT an a a b or a c

\([^<]*\) continue to match any characters until it match a <. The < will not be included. \( \) will save what it got matched and \1 will display it for you.
