how to access attributes from XML nodes

[robinmurphy]

I am trying to access the values of attributes within my XML nodes using a converter within the XStreamMarshaller. I am able to read the nodes and the values of those nodes but have been unable to access the attributes - they return a null value.

this is the code from my application context:
.............
<bean id="xmlmarshaller" class="org.springframework.oxm.xstream.XStreamMars haller">
<property name="aliases">
<util:map id="aliases">
<entry key="statement" value="com.batch.xmltask.XmlInputData" />
</util:map>
</property>
<property name="converters" ref="headerConverter" />
</bean>

<!-- Converters -->
<bean id="headerConverter" class="com.batch.converters.HeaderConverter" />
.............

the xml file that I am reading is as below:

...........
<statement header="N0000|NEWCUSTOMER STATEMENT|">
<accountNumber header="B1009">23</accountNumber>
<customerName header="B1002">julius</customerName>
<addressLine1 header="B1003"></addressLine1>
<addressLine2 header="B1004"></addressLine2>
<addressLine3 header="B1005"></addressLine3>
<addressLine4 header="B1006"></addressLine4>
<zip header="B1007" />
<statementDate header="B1010" />
</statement>
..........

the attribute I am trying to read is 'header' and this is the code from my converter:

public class HeaderConverter implements Converter {

..............@Override
public Object unmarshal(HierarchicalStreamReader reader, UnmarshallingContext context) {
XmlInputData inputData = new XmlInputData();
System.out.println(reader.getAttribute("header"));
System.out.println(reader.getNodeName());
while (reader.hasMoreChildren()) {
reader.moveDown();
System.out.println(reader.getNodeName());
System.out.println(reader.getAttribute("header"));
reader.moveUp();
}
return inputData;
}
...............
}

and this is the output after running a test case:

4:53:46,851 INFO SimpleJobLauncher:109 - Job: [FlowJob: [name=simpleJob]] launched with the following parameters: [{}]
14:53:46,881 INFO AbstractJob:347 - Executing step: [TaskletStep: [name=step1]]
null
statement
accountNumber
null
customerName
null
addressLine1
null
addressLine2
null
addressLine3
null
addressLine4
null
zip
null
statementDate
null
.................

thanks in advance!

I managed to resolve this by using reader.getAttribute(0) instead of reader.getAttribute("header") - seems like a bug in XStreamMarshaller
