The pipeline:parameter element specifies the name and value of each parameter. The value may be passed as a DCI expression using the value attribute or as body content if it is a text element or complex infoset.
The pipeline:parameter element specifies the name and value of each parameter. The value may be passed as a DCI expression using the value attribute or as body content if it is a text element or complex infoset.
You can define a single pipeline:parameters element as the first child of a pipeline:transform. It can contain one or more pipeline:parameter elements. All the XSL transforms that you refer to in the related pipeline:transformation elements must declare a xsl:param element with a name matching each of the pipeline parameters.
The example demonstrates a transform element with a parameter block declared:
<?xml version="1.0" encoding="UTF-8"?>
<html xmlns="http://www.w3.org/2002/06/xhtml2"
xmlns:pipeline="http://www.volantis.com/xmlns/marlin-pipeline"
xmlns:webd="http://www.volantis.com/xmlns/marlin-web-driver">
<head>
<title>pipeline:parameters</title>
</head>
<body>
<div>
<pipeline:transform>
<pipeline:parameters>
<pipeline:parameter name="header_param" value="Welcome to Seattle"/>
</pipeline:parameters>
<pipeline:transformation href="test.xsl"/>
<webd:get url="http://weather.yahooapis.com/forecastrss">
<webd:parameters>
<webd:parameter name="p" value="USWA0395"/>
<webd:parameter name="u" value="c"/>
</webd:parameters>
</webd:get>
</pipeline:transform>
</div>
</body>
</html>The transform references the stylesheet test.xsl. It defines the global xsl:param name 'header_param' that is later referenced in the template like any other XSL parameter or variable, and output as a header.
The names of the pipeline parameters match an equivalent xsl:param element in the stylesheet that follows. If the transform element contained multiple transformation elements the parameters would be passed to the stylesheet for each transformation.
