XProc steps
A | B | C | D | E | F | G | H | I | J | K | L | M | N | O | P | Q | R | S | T | U | V | W | X | Y | Z
p:group
<p:group name? = NCName>
((p:output |
p:log)*,
subpipeline)
</p:group>
<p:group> is a so-called wrapper for an accumulation of several steps. It unites the steps. For example, it has to be used in the <p:try> Multi-Container Step within the "try" area.
Example
In the following example a <p:group> step is demonstrated.
<?xml version="1.0" encoding="UTF-8"?>
<p:declare-step xmlns:p="http://www.w3.org/ns/xproc" xmlns:c="http://www.w3.org/ns/xproc-step" version="1.0">
<p:input port="source">
<p:empty/>
</p:input>
<p:output port="result"/>
<p:group>
<p:identity>
<p:input port="source">
<p:inline>
<doc>Example</doc>
</p:inline>
</p:input>
</p:identity>
</p:group>
<p:identity/>
</p:declare-step>
In the present example, the <p:identity> step is enclosed with a <p:group> element. The shown source text shall only demonstrate the application of the step.
