Key: SYNAPSE-198
URL: https://issues.apache.org/jira/browse/SYNAPSE-198
Project: Synapse
Issue Type: Bug
Components: Core
Affects Versions: 1.1
Environment: Ubuntu7.04, JDK1.5.0_12
Reporter: Evanthika Amarasiri
Fix For: 1.1.1-QA-B1
Created a sequence as below and invoked a client but the expression returns a
text node and not the actual value of the specified expression.
<sequence statistics="enable" name="xquery_calc">
<in>
<xquery key="xquery-key-req-add">
<variable xmlns:m0="http://calc.math.com";
xmlns:ns1="http://org.apache.synapse/xsd";
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"; name="x"
expression="self::node()//m0:add/m0:x/child::text()" type="INTEGER"/>
<variable xmlns:m0="http://calc.math.com";
xmlns:ns1="http://org.apache.synapse/xsd";
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"; name="y"
expression="self::node()//m0:add/m0:y/child::text()" type="INTEGER"/>
</xquery>
<send>
<endpoint>
<address uri="http://localhost:9000/soap/Calculator"/>
</endpoint>
</send>
</in>
<out>
<xquery key="xquery-key-res-add">
<variable xmlns:m0="http://calc.math.com";
xmlns:ns1="http://org.apache.synapse/xsd";
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"; name="return"
expression="//m0:addResponse/m0:return/child::text()" type="INT"/>
</xquery>
<send/>
</out>
</sequence>
