    Here is the configuration of the "Read XML" operator which works for the data you have posted:

    <?xml version="1.0" encoding="UTF-8" standalone="no"?>
    <process version="5.3.005">
      <operator activated="true" class="process" compatibility="5.3.005" expanded="true" name="Process">
        <process expanded="true">
          <operator activated="true" class="read_xml" compatibility="5.3.005" expanded="true" height="60" name="Read XML" width="90" x="45" y="30">
            <parameter key="file" value="/home/marcin/temp/forum.xml"/>
            <parameter key="xpath_for_examples" value="//div[@id='features']/ul/li"/>
            <enumeration key="xpaths_for_attributes">
              <parameter key="xpath_for_attribute" value="text()"/>
            <list key="namespaces"/>
            <parameter key="use_default_namespace" value="false"/>
            <list key="annotations"/>
            <list key="data_set_meta_data_information">
              <parameter key="0" value="Attribute.true.polynominal.attribute"/>
          <connect from_op="Read XML" from_port="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"/>
