Please use code tags as required by forum rules!

Try
Code:
awk     '/<name>GoogleOverhaul<\/name>/ {L=1}
         /<\/widget>/                   {L=0}
         L && /staging.*on/             {sub(/>on</,">off<")}
         1
        ' global.xml

Code:
sed -i 's:<status environment="staging">on</status>:<status environment="staging">off</status>:' global.xml

Try
Code:
awk '$1=="name" {f=($2=="GoogleOverhaul")?1:0} f && $1~/"staging"/{$2="off"}1' RS=\< ORS=\< FS=\> OFS=\> file

If it gets more complicated it may be better to use specializer XML tooling....

@balajesuri: that will change all staging elements to "off"
