Shell Programming and Scripting

Sorry, I should have made it clear in my first post.

The xml itself is a big file, so unfortunately I can't try the echo option. Also the insert/update should be committed using the solution.

To re-iterate:

Code:

<Date="" Node1="50" Groups="20">

is a part of a big xml file Config.xml and I am trying to insert/update the Date field and commit the changes.

Reason for Insert/update option
1) Insert: The Date field could be blank (Date="")
2) Update: xml could already have a date in it ((Date="20120610")). So the command should replace it.


something like this

Code:

#! /bin/ksh
dt=20120701
sed -e 's/Date=.*"/Date=$dt/' Config.xml

Hi,

Can someone please help with my query?

Thanks

I don't think anyone has suggested to use echo to solve your problem. What they have done is to demonstrate methods to tackle your problem using the only data you have provided.

Anyway, you can use something like:

Code:

sed '/<Date=.*Node1=.*Groups.*>/s/<Date="[^"]*"/<Date="20120712"/g' inputfile > temp
mv temp inputfile

Sorry if you read the earlier post, you could see solutions based on 'echo'. That's why I corrected my statement in the later post saying its a big xml file and 'echo' doesn't suit.

Anyways thanks for the new solution with <Date="[^"]*"

Cheers
Vivek

For the benefit of users of the forum, here is my final solution

Code:

sed -i 's/Date="[^"]*"/Date="20120712"/' Config.xml
