Render XML

Render XML is a synchronous activity that takes an instance of an XML schema element and renders it as a stream of bytes containing XML or an XML string.

Rendering Date and Datetime Strings

The Render XML activity takes an instance of an XML schema element and renders it as a stream of bytes containing XML or an XML string. The schema is processed based on the XSD file specified.

UTC time is used when datetime strings are generated. For example, the time 55 minutes, 31 seconds, and 112 milliseconds after 2.00 p.m.on February 10th, 2002 would be represented by the Render XML activity as 2002-02-10T14:55:31.112Z

The General tab has the following fields.

Field Literal Value/Process Property/Module Property? Description
Name No The name to be displayed as the label for the activity in the process.
Output Style No Specifies whether the output should be text or binary data.
Format Using Default Namespace Prefix No Prepends the namespace with the default namespace prefix.
Encoding Yes This field is available only when the Output Style field is set to text. This field specifies the encoding value to place into the XML header of the rendered XML data.

You can specify any valid XML encoding value listed in IANA-Charsets.

Description

Provide a short description for the activity.

Advanced

Click the Advanced tab and specify which elements in the input schema can contain CDATA sections. Using CDATA sections you can enclose text within an element that should not be treated as XML.

Click the + button to add elements of the input schema to the list. When you click the + button, a dialog displays. Using this dialog locate and select the input schema by location in the project or by namespace. Use the By Location tab if your input schema is located in the project directory. Use the By Namespace tab if you constructed the input schema on the Input Editor tab.

Use the X button to remove the elements from the list and the up and down arrows to move elements in the list.

Input Editor

From the Input Editor tab you can define a schema for the incoming XML data you want to render.

The following is the input for the activity.

Input Item Type Description
byteEncoding string This is only available when you set the Output Style field in the General tab to binary.

This specified the encoding value to place into the XML header in the rendered XML output. This is also the encoding used to encode the binary data. If this item is not specified, the default encoding of the java virtual machine used by the process engine is used to encode the binary data. This value may not be a valid XML encoding.

You can specify any valid XML encoding value listed in IANA-Charset. See http://www.iana.org/assignments/character-sets for a complete list. The encoding names are case sensitive.

XML Schema string The XML schema to render. The contents of the schema are determined by the schema specified in the Input Editor tab.

Output

The following is the output of the activity.

Output Item Type Description
xmlString string Available when text is selected in the Output Style field in the General tab. This item contains a stream of bytes representing the rendered XML.
xmlBytes bytes Available when binary is selected in the Output Style field in the General tab. This item contains a stream of bytes representing the rendered XML.

Fault Thrown When..
