Problems with SED

I have a group of xml files and I need to insert 3 parameters just after this line in each file:
---------------Pattern to be searched for-------------------------
<!--The following configuration is a test configuration-->

---------------Parameters to be added---------------------------
<Parameter>
<Name>NamedThreadsEnableLocking</Name>
<Value>true</Value>
</Parameter>

<Parameter>
<Name>Test1</Name>
<Value>true</Value>
</Parameter>

<Parameter>
<Name>Test2</Name>
<Value>true</Value>
</Parameter>

Can anyone help me implement this with the sed command? Thanks in advance.

Say the params to be added are put in param.txt.

Code:
sed -e '/<!--The following configuration is a test configuration-->/r param.txt' input.xml > output.new.xml

Hi Vino,

This is wonderful use of sed. I have another query on the same situation, What if i need to append or insert a few more lines BEFORE a particualr string.

How can i do that?

Cheers !!!

Read those few lines into a variable e.g. EXAMPLE.

Sed for that particular string, say it is "welcome to the unix forums".

Code:
sed -e "s_welcome to the unix forums_$EXAMPLE\n&_g" input.txt

Not tested.

Vino,

Thanks for that. But one problem.

It adds the word "append.txt", What i need to do is add the contents of append.txt in that position.

Thanks
