More about XML Stream rules |
Process Commander does not check whether the document produced from applying an XML stream rule is well-formed, nor does it validate the document against a DTD or XSDL.
In fact, the document may contain simple text, and not contain angle bracket characters (< >) or other XML syntax. For example, you can create and write out a text file using an XML Stream rule, the Property-Set-XML method, and the WriteFileOutput() function. CLINIC 4/26/05
If you are entering XML code directly (Auto-generated XML is not checked) and your workstation has an XML editor, you can set up the open authoring feature to help you compose your XML code. If you don't designate an editor, the system uses Windows Notepad.
To include the value of a property, use the <pega:reference >
JSP tag. TURBT CLINB 12/12/03 In most cases, include the
normal
mode in each reference
JSP tag. For
example:
<pega:reference name="pyWorkpage.pyStatusWork" mode="normal" />
This causes stream processing to replace any < and > characters
that may appear the corresponding entities <
and
>
, and (unlike the default display
mode)
does not add a space before and after the property value.
However, if the property value contains XML markup, use the literal directive:
{literal TheXMLdoc }
or the equivalent literal mode for the reference tag:
<pega:reference name=".TheXMLdoc" mode="literal" />
These suppresses stream processing of the value.
You can use other JSP tags (such as include, Java, and foreach) within the XML text. Processing of JSP tags in XML is identical to JSP tags in HTML.
When you save an XML stream rule, the system converts your XML text and JSP tags or directives to Java source code. As a learning or debugging aid, you can review this Java code.
C-1665Click the Show Java toolbar button () to see the system-generated Java code that implements the XML Stream rule. The window presents a read-only preview of the Java that implements this rule instance. This Java code is not identical to the Java that is executed at runtime, which includes Java code inlined from other rule instances and reflects rules in the requestor's RuleSet list.
To trace the start and end of XML stream rule executions, select the Stream Rules checkbox in the Rule Types to Trace area of the Trace Options panel. See Tracer — Setting Options.
The Rule-Obj-XML class is not derived from the Rule-Obj- abstract class. The immediate parent class of the Rule-Obj-XML class is the Rule-Stream class.
