Hi,

I have a read xml task that reads an xml file and output data into a rowset variable with columns defined like the xml file. I created a ForEachLoop with Items Variable as name of the rowset ${Tokens} and Current Item Variable as Row. But when I execute my project, the ForEachLoop ends with the below message:
(Read xml task completes successfully, but the Loop encounter an error)

Reading the XML file is just a matter of utilizing a Well-Formed XML file and identifying the path to the values you need to retrieve.

The example that was sent for the ResponseCode/ResponseMessage ... would look something like this:
Code: Select all
<project name="ReadXML" mainModule="Main" version="2.0" logLevel="debug">

       <module name="Main">

              <xmlRead label="Read Response XML" file="C:\Users\relliott\Documents\Customers\Gensys\TokenResponse2.xml" defaultTrim="both" version="1.0" logLevel="verbose" disabled="false">
                     <rowset name="response" nestedSharedValues="false">
                           <column index="1" value="/soap:Envelope/soap:Body/GetRecentlyModifiedTokensResponse/response/ResponseCode"    name="ResponseCode" />
                           <column index="2" value="/soap:Envelope/soap:Body/GetRecentlyModifiedTokensResponse/response/ResponseMessage" name="ResponseMessage" />
                     </rowset>
              </xmlRead>

              <forEachLoop label="Display Responses" itemsVariable="${response}" currentItemVariable="currentItem" beginIndex="1" endIndex="1" logLevel="debug" disabled="false">

                     <setVariable label="Set ResponseCode"    name="ResponseCode"     value="${currentItem[1]}" version="2.0" />
                     <setVariable label="Set ResponseMessage" name="ResponseMessage"  value="${currentItem[2]}" version="2.0" />

                     <print label="Show Information" version="1.0">
                           <![CDATA[
===============================================
ResponseCode:     ${ ResponseCode }
ResponseMessage:  ${ ResponseMessage }
===============================================
        ]]>
                     </print>

              </forEachLoop>
       </module>

</project>
This is based on the XML file as such:
Code: Select all
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <soap:Body>
    <GetRecentlyModifiedTokensResponse xmlns="urn:Eve_1_4_4">
      <GetRecentlyModifiedTokensResult />
      <response>
        <ResponseCode>ERROR</ResponseCode>
        <ResponseMessage>invalid login</ResponseMessage>
      </response>
    </GetRecentlyModifiedTokensResponse>
  </soap:Body>
</soap:Envelope>
The Job Log from the execution of this project looks like this:
Code: Select all

I did the above, but except for Row[1], all other values are returning as null. Eg. Row[2] , Row[3]..Row[28]. But I do have data in the input xml file for Row[2] and many other elements in the rowset. Please help.

I found out the error, it was a typo on the xml path to get the data.
