XML Input: Stage tab
Specify XML Input stage properties in the stage tab.
Under Properties, set properties for validating the XML data, logging
errors, and grammar caching. The XML Input stage checks for well-formed XML and optionally checks
that the data conforms to a referenced XML schema. To use default values for elements and attributes
in the output data, you must specify a schema in your XML input data via the
schemaLocation attribute within the root element tag.
The XML parser compiles the validating schema to create a schema grammar. While validating the grammar, the parser can apply extra steps called full schema constraint checking, which may increase processing time and be memory-intensive. To enable this checking, select the Strict option under XML validation level. To disable this type of validation, use the Default option.
If your job processes two or more XML documents that use the same schema, you can avoid recompiling the schema by caching the grammar. Select Enable grammar caching to cache the grammar.
Define mappings between the Xalan XSLT processor and DataStage to determine how parsing messages and faulty XML documents are processed. Assign fatal errors, non-fatal-errors, and warnings to one of the error levels in the following table.
| DataStage error level | Result |
|---|---|
| Reject | Faulty document rows and messages can be written to a Reject link, if one exists. You can also send the messages to the job log. |
| Fatal | The job terminates, and the messages are written to the job log. |
| Warning | A warning message is written to the job log. |
| Info | An information message is written to the job log. |
| Trace | Debug and monitoring information is written to the job log. |
Under Transformation, set output value properties for the XML Input stage. Use the Load box to write XPath expressions. See Transformation settings for more information.
