wso2esb enrich mediator deletes node soap:Header - soap

Question

I have 2 child wsse:Security in soap:Header and trying to delete one. I tried to do this with Enrich Mediator, but instead of replace soap:Header it deletes. Here is simple example that reproduces it:
<inSequence>
<enrich>
<source type="inline" clone="true">
<soapenv:Header xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<foo/>
</soapenv:Header>
</source>
<target xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xpath="//soapenv:Header"/>
</enrich>
<log level="full"/>
</inSequence>
Log mediator logs message without Header. If I add to target action="child", everything work just as expected. So i have 2 questions:
1. Why enrich mediator act like that?
2. How can i change header with other way?

Answer 1

You should use header mediator to change SOAP Headers
Have a look there : https://docs.wso2.com/display/ESB481/Header+Mediator
Sample to add a custom header :
<header xmlns:myns="http://com/header" name="myns:MyHeader" value="0"/>
Sample to remove it :
<header xmlns:myns="http://com/header" name="myns:MyHeader" action="remove"/>
You can use this mediator to change http headers : just add a scope attribute with a value equals to 'transport'
