Purpose

This lets you run python-like if conditions within rml. This uses the dynamic rml dtd. See the relevant rml sample here.

Example usage

<!DOCTYPE document SYSTEM "../dynamic_rml.dtd">
<document filename='test_020_dynamic.pdf'>
    ...
    <story>
        <script_b>x = False</script_b>
        <if_b cond="not x">
            <loop_b var="v" in="(1,2),(3,4),(5,6),(7,8),(9,10)">
                <para><expr>v[0]</expr>: <expr>v[1]</expr></para>
            </loop_b>
        </if_b>
    </story>
</document>

Note: Only relevant sections are used in this snippet. Some tags were not included. See some of our samples for further insight of how you may go about setting up a full document using rml.
