2.10.3.2.2 Automatic Conversion and Xerces Parser XML Validation

The Xerces parser uses default attribute settings to control XML validation during automatic conversion. However, Tuxedo supports 14 specific Xerces DOMParser class attributes that provide some automatic conversion customizing flexibility.

If you are using the automatic conversion method, parser validation is determined one of two ways:

• Accepting the default parser validation settings
• Specifying validation options through the TPXPARSFILE environment variable

The TPXPARSFILE environment variable designates the fully qualified path to a text file that contains the XercesDOMParser class attribute settings you want to modify.

Each attribute in the text file is written on a separate line in the following format:

<parser attribute>=<setting>

The <parser attribute> can be any or all of the 14 parser attributes in the following table, where (D) denotes the default setting.

Note:

For a detailed description of these attributes, see Xerces parser 3.2.3 documentation.

Parser Attribute	Setting
CacheGrammarFromParse	True or False (D)
DoNameSpaces	True or False (D)
DoSchema	True or False (D)
ExternalSchemaLocation	Fully qualified path to file_name.xsd
ExitOnFirstFatalError	True or False (D)
IncludeIgnorableWhiteSpace	True or False (D)
LoadGrammar	Fully qualified name of validating file
NoNamespaceSchemaLocation	Fully qualified path to file_name.xsd
StandardUriConformant	True or False (D)
UseCachedGrammarInParse	True or False (D)
UseScanner	WF, DG, SG, or IG (D)
ValidationConstraintFatal	True or False (D)
ValidationScheme	Val_Never, Val_Always, or Val_Auto (D)
ValidationSchemaFullChecking	True or False (D)

The following listing is a sample input plain text file for the TPXPARSFILE environment variable.
