Camel LOOP

[contactreji]

Hi

Basically, I am trying to develop a module which pushes the customer records
into database. Incoming XML contains multiple customer records.

I am wondering how I can use the CamelLoopIndex property while looping
through xml records.
I have some code like follows.

I want to loop through records while parsing them using Xpath expressions to
set them into the exchange property which later be used in camel sql insert
statement.

Can someone give me the syntax? Do I have to put the xpath expression inside
the camel simple to access the property CamelLoopIndex ??
*
<camel:when>
<camel:simple>${in.header.operationName} ==
'CreateOperation'</camel:simple>
<camel:loop>


<camel:xpath>count(//CustomerRecords/Record[${in.header.CamelLoopIndex}]/Cust_ID/text())</camel:xpath>
<camel:setProperty propertyName="customerID">
<camel:xpath>//CustomerRecords/Record/Cust_ID/text()</camel:xpath>
</camel:setProperty>
<camel:setProperty propertyName="customerName">
<camel:xpath>//CustomerRecords/Record/Cust_Name/text()</camel:xpath>
</camel:setProperty>
<camel:setProperty propertyName="customerAddress">

<camel:xpath>//CustomerRecords/Record/Cust_Address/text()</camel:xpath>
</camel:setProperty>
<camel:setProperty propertyName="customerBalance">

<camel:xpath>//CustomerRecords/Record/Cust_Balance/text()</camel:xpath>
</camel:setProperty>
<camel:setProperty propertyName="customerPhoneNo">
<camel:xpath>//CustomerRecords/Record/Cust_Phone/text()</camel:xpath>
</camel:setProperty>
<camel:setProperty propertyName="customerPostalPIN">
<camel:xpath>//CustomerRecords/Record/Cust_PIN/text()</camel:xpath>
</camel:setProperty>
<camel:setBody>
<camel:simple>insert into customer
values('${property.customerID}','${property.customerName}','${property.customerAddress}','${property.customerBalance}','${property.customerPhoneNo}','${property.customerPostalPIN}')</camel:simple>
</camel:setBody>
<camel:to uri="jdbc:dataSource" />
</camel:loop>
</camel:when>*

And I tried using Xquery this way

* <camel:when>
<camel:simple>${in.header.operationName} ==
'CreateOperation'</camel:simple>
<camel:setProperty propertyName="recordCount">
<camel:xquery>count(//CustomerRecords/Record)</camel:xquery>
</camel:setProperty>
<camel:log message="Count = ${property.recordCount}"
loggingLevel="INFO" logName="Log" />*

it returns following exception

org.w3c.dom.DOMException: HIERARCHY_REQUEST_ERR: An attempt was made to
insert a node where it is not permitted.

The incoming XML is as follows
*<soapenv:Envelope
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Header/>
<soapenv:Body>
<CustomerRecords>

<Record>
<Cust_ID>1010</Cust_ID>
<Cust_Name>REJI MATHEWS</Cust_Name>
<Cust_Address>7TH MAIN, BANGALORE</Cust_Address>
<Cust_Balance>1000</Cust_Balance>
<Cust_Phone>+4231213</Cust_Phone>
<Cust_PIN>560043</Cust_PIN>
</Record>
<Record>
<Cust_ID>1004</Cust_ID>
<Cust_Name>REJI MATHEWS</Cust_Name>
<Cust_Address>7TH MAIN, BANASAWADI, BANGALORE</Cust_Address>
<Cust_Balance>1000</Cust_Balance>
<Cust_Phone>+23232</Cust_Phone>
<Cust_PIN>560043</Cust_PIN>
</Record>

<Record>
<Cust_ID>1006</Cust_ID>
<Cust_Name>REJI MATHEWS</Cust_Name>
<Cust_Address>7TH MAIN, BANGALORE</Cust_Address>
<Cust_Balance>1000</Cust_Balance>
<Cust_Phone>123</Cust_Phone>
<Cust_PIN>560043</Cust_PIN>
</Record>

</CustomerRecords>
</soapenv:Body>
</soapenv:Envelope>*
