Use p:pipe to connect the source port of the exec command to the source port on your declared step, like this: <p:declare-step name="main" type="tidy:html"> <p:input port="source"/> <p:output port="result"/> <p:option name="href"/> <p:exec command="tidy" source-is-xml="true" result-is-xml="false" wrap-result-lines="false" method="xml"> <p:input port="source"> <p:pipe step="main" port="source"/> </p:input> <p:with-option name="args" select="'--quiet yes --show-warnings no --doctype omit --numeric-entities yes --output-xml yes'"/> </p:exec> <p:unescape-markup/> <p:unwrap match="c:result"/> </p:declare-step> Note that I added a name to your declare step and changed source-is-xml to true. If you're reading a document flowing through a pipeline, then it is XML. Since the source is the default readable port, you could also do this: <p:declare-step type="tidy:html"> <p:input port="source"/> <p:output port="result"/> <p:option name="href"/> <p:exec command="tidy" source-is-xml="true" result-is-xml="false" wrap-result-lines="false" method="xml"> <p:with-option name="args" select="'--quiet yes --show-warnings no --doctype omit --numeric-entities yes --output-xml yes'"/> </p:exec> By default, the source port on p:exec will be connected to the default readable port, which is the source port on your declare step in this case.
