Shell Programming and Scripting

Dear Friends,
Please tell me the shell command to find desired string in a file....
for example,

file1.txt contains following text(please note that all the following tags are in single line)
----------------------------
<aaa> some text1</aaa><bbb> some text2</bbb><ccc> some text3</ccc><kkk>W/X12345</kkk><ddd> some text4</ddd><eee> some text5</eee><fff> some text6</fff><ggg> some text7</ggg><hhh> some text8</hhh>
----------------------------
please tell me how to extract "W/X12345" from the above file content..?
this paramenter,W/X12345, length may not be constant, some times it may be
W/X123
or
W/X87789989
or
W/X90798897989
ect...
please tell me how do I get this paramenter?

Please help as soon as possible.

Thanks in Advance..

Try this :

Code:

sed -n '/<kkk>/s/.*<kkk>\(.*\)<\/kkk>.*/\1/p' file1.txt

Dear aigles, thanks for ur reply,
but I am very sorry, I have missed one important point in my previous mail.
please pardon me for that.

file1.txt contains following text(please note that all the following tags are in single line)
----------------------------
<aaa> some text1</aaa><bbb> some text2</bbb><ccc> some text3</ccc><kkk>W/X12345</kkk><ddd> some text4</ddd><eee> some text5</eee><fff> some text6</fff><kkk>3333</kkk><ggg> some text7</ggg><hhh> some text8</hhh>
----------------------------
please see that above file conatins "<kkk>" twice. i.e.,
<kkk>W/X12345</kkk>
and
<kkk>3333</kkk>

I have to extract the entire string that starts with "W/X" till the end tag("</kkk>")
i.e., I need to extract "W/X12345"

this paramenter,W/X12345, length may not be constant, some times it may be
W/X123
or
W/X87789989
or
W/X90798897989
ect...
please tell me how do I get this paramenter?


waiting for ur reply,
