how can i convert below Xml syntax in Nextflow

how can i convert below Xml syntax in Nextflow.

<collection name="parallel_params"/>
<action name="create_parallel_params">
    <input port="workflowParameters" collection="workflowParameters"/>
    <output port="parallel_params" collection="parallel_params"/>
</action>

I have written nextflow code as below:

process create_parallel_params{
    publishDir params.publishDir, mode: 'copy'
    container 'ubuntu:latest'
    input:
    file workflowParameters from Channel.fromPath(params.workflowParameters)
    output:
    file 'parallel_params.tsv' into parallel_params

    script:
    """
    python $TOOL_FOLDERS/parallel_paramgen.py $workflowParameters
    """

}
