SOLVED: Simple question about multiple RSS feed

I notice the Read RSS Feed operator takes no inputs.  

I ask because I am attempting to load a list of rss feeds (URL's) from Excel or a database, loop through the Excel sheet (~80 entries), read each feed & store each feed result into a datasheet, continuing until finished.  This should be a simple looping (Loop Values operator) process, but I can do this only by re-entering in each rss feed URL manually, since the RSS Feed operator permits no operation or parameters passed to it.

Suggestions?

    Hi there,

    Though the little beastie takes no inputs it has to take notice of its parameters, and that's where you can slip in your macro, in a loop, like this... 
    <?xml version="1.0" encoding="UTF-8" standalone="no"?>
    <process version="5.2.003">
      <context>
        <input/>
        <output/>
        <macros/>
      </context>
      <operator activated="true" class="process" compatibility="5.2.003" expanded="true" name="Process">
        <process expanded="true" height="198" width="522">
          <operator activated="true" class="retrieve" compatibility="5.2.003" expanded="true" height="60" name="Retrieve" width="90" x="45" y="30">
            <parameter key="repository_entry" value="//Samples/data/Iris"/>
          </operator>
          <operator activated="true" class="loop_values" compatibility="5.2.003" expanded="true" height="76" name="Loop Values" width="90" x="179" y="30">
            <parameter key="attribute" value="label"/>
            <process expanded="true" height="216" width="540">
              <operator activated="true" class="web:read_rss" compatibility="5.1.004" expanded="true" height="60" name="Read RSS Feed" width="90" x="112" y="30">
                <parameter key="url" value="http://www.rsssearchhub.com/feeds/?search=%{loop_value}&amp;amp;action=Search+Feeds"/>
                <parameter key="random_user_agent" value="true"/>
              </operator>
              <connect from_op="Read RSS Feed" from_port="output" to_port="out 1"/>
              <portSpacing port="source_example set" spacing="0"/>
              <portSpacing port="sink_out 1" spacing="0"/>
              <portSpacing port="sink_out 2" spacing="0"/>
            </process>
          </operator>
          <connect from_op="Retrieve" from_port="output" to_op="Loop Values" to_port="example set"/>
          <connect from_op="Loop Values" from_port="out 1" to_port="result 1"/>
          <portSpacing port="source_input 1" spacing="0"/>
          <portSpacing port="sink_result 1" spacing="0"/>
          <portSpacing port="sink_result 2" spacing="0"/>
        </process>
      </operator>
    </process>
    Hope that's in the right direction anyway.

    OP
    Thanks for the lead, Haddock, but I believe that it's probably better to use a feed mashup/aggregator for now.  Yahoo Pipes and others will do this, and then feed to Rapid Miner.

    I was hoping that RM could allow input into the RSS Reader process, but perhaps this will turn out to be a new feature request.  I wish I was better at Java/XML.


    (PS Love your reference to Tintin).
