Please could somebody tell me how to exclude two attributes by name. I've managed to exclude one attribute using an attribute filter and selecting attribute name filter, but the A && B syntax described in the manual doesn't seem to work. Thanks, and sorry my first post is so inane

    Hi there,

    No probs on in(s)anity, I've done a ludicrous number of posts and conclude that the more you do the worse it gets. You can use a regex filter to zap attributes. Here's how to extract att1 and att2 by name...
    <?xml version="1.0" encoding="UTF-8" standalone="no"?>
    <process version="5.0">
      <context>
        <input>
          <location/>
        </input>
        <output>
          <location/>
          <location/>
        </output>
        <macros/>
      </context>
      <operator activated="true" class="process" expanded="true" name="Process">
        <process expanded="true" height="-20" width="-50">
          <operator activated="true" class="generate_data" expanded="true" height="60" name="Generate Data" width="90" x="50" y="69"/>
          <operator activated="true" class="select_attributes" expanded="true" height="76" name="Select Attributes" width="90" x="277" y="66">
            <parameter key="attribute_filter_type" value="regular_expression"/>
            <parameter key="regular_expression" value="att1|att2"/>
            <parameter key="invert_selection" value="true"/>
          </operator>
          <connect from_op="Generate Data" from_port="output" to_op="Select Attributes" to_port="example set input"/>
          <connect from_op="Select Attributes" from_port="example set output" 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>
