Parse XML to get IP Adresses Only Using Bash

arvinarvin · 07-28-2010, 09:55 AM

a bash noob here.

I got this xml
...
<other stuff="etc">...</other>
<cluster id="1">
<host ipaddress="192.168.50.1" name="server1">
<host ipaddress="192.168.50.2" name="server2">
<host ipaddress="192.168.50.3" name="server3">
</cluster>
...

how would i get the ip addresses only using bash.

Thanks In Advance

Code:

#!/bin/bash
while read -r line
do
  case "$line" in
   "<host ipaddress"* )
        line="${line/<host ipaddress=\"/}"
        echo ${line%%\"*}
  esac
done <"file"

XML is not a line-oriented language while tools called from 'bash' typically are.

Use Perl (for example) and its module to do the job. Don't reienvent the wheel.

Or you could throw an awk at it:

Code:

awk -F"\"" '/<host ipaddress/{print $2}' file
