Hi,

I want to do the following

Assume there is an xml which contains entries like the following...

<a attr1="value1" attr2="value2"/>
<b attr1="value3" attr2="value4" attr3="value5"/>
<a attr1="value1" attr2="value2"/>
....


I want to replace the "attr1" to say "attr3" in every occurence of <a/> tag.

I need the result to be something like

<a attr3="value1" attr2="value2"/>
<b attr1="value3" attr2="value4" attr3="value5"/>
<a attr3="value1" attr2="value2"/>
....

Is there any tool to do the above?
Any shell scripts?

Please reply...

Thanks and Regards,

you can use sed on command line or inside of a script this way:

sed -e '/<a attr1/s/attr1/attr3/' file.xml > file.temp
mv file.temp file.xml

Hi ducasio,

My example was simple enough. Actually I wanted something like this

<a attr1="value1" attr2="value2"/>
<b attr2="value4" attr1="value3" attr5="value5"/>
<a attr2="value2" attr1="value1"/>
<a attr4="valueN" attr2="value2" .....attr1="valueX"... />

The attr1 need not be placed near start tag <a>. Hence to search by pattern that attr1 is always adjacent to <a> should not be there.

In such a case how do we go about doing it?

Please reply.

Sriram,

You have to look for /<a/ patterns and then put attr3 instead of attr1.
It seems pretty straightforward to reach there from ducasio's script.
