How to change the content of the alert scalation emails

Hello.

I need send an email ONLY with the text writed in the text Message of the Escalation Email Detail. The email that sends openmanager has information that is not necessary (and it's problematic).

Message : <sms>
<user>user_test</user>
<password>123Fc</password>
<dst>
<num>+34624205614</num>
</dst>
<txt>Alert Test</txt>
</sms>

I need that this email only have the content that have the text message:

<sms>
<user>user_test</user>
<password>123Fc</password>
<dst>
<num>+34624205614</num>
</dst>
<txt>Alert Test</txt>
</sms>

It's possible?

Thanks.
