使用脚本提取文本

Question

We have an xml file of the following format:

<mailBox>
...
</mailBox>
<mailBox>demon</mailBox>
<tz>16385</tz>
<Contact>
....
</Contact>
</mailBox>
<mailBox>
...
</mailBox>

Is there a way to extract a particular node out of this xml using a sed/awk/grep one-liner?
I was looking for somethign in the format

`sed -n 'mailBox\>demon,......p`

Answer 1

on your sample the tag demon is on the same line and not in rest of file. Error or specific

If it's an error (so mailbox tag are on separate lines)

sed -n '1h;1!H;${x
s/.*\(<mailBox>demon.*\)/\1/;s|</mailBox>.*||;p
}' YourFile

Answer 2

您可以尝试：

perl -0777 -nE 'foreach (/<mailBox>(.*?)<\/mailBox>/sg) {say $_}' file
