When I return to check result of "test-result.xml", it will show out it has only one bunch of delivery node existed. It suppose to have few bunch of delivery node exists but it just be able to capture last nodes the end of loop process.
<Do>
<delivery>
<dono>DM202423</dono>
<custcode>M15</custcode>
<custname>A Company</custname>
<stockcode>ZPPFERG</stockcode>
<stockdesc>PRECISCO ENVELOPE</stockdesc>
<unitprice>0.8200</unitprice>
<qty>200</qty>
<amount>164.00</amount>
</delivery>
</Do>
Anyone could help me to solve my problems by create out a array buffer at inside class doinfo, so I could capture every single string object in memory for further print out into xml file.
