XML Support
OpenROAD application and source components now can be exported to and imported from XML in UTF-8 or UTF-16 encoding. The XML file format:
• Is human readable
• Produces clean differences between different revisions of a file
• Allows changes to be merged
• Enables OpenROAD source components to be managed by a variety of Software Configuration Management (SCM) systems
You can use XML export as an alternative to the documentapp utility to provide consistently structured output that uses documented attribute and class names. Another advantage to exporting applications and components to XML is that exported data does not require storage internal to OpenROAD.
You can use outputted XML to perform bulk attribute changes for all or selected components and applications, re-importing the modified XML files when your changes are complete. Using the new system classes, you also can generate and parse arbitrary XML files, extending OpenROAD’s scripting capabilities.
OpenROAD applications and components can be created or edited outside of the Workbench IDE using third-party editors, OO-CASE/UML tools, Model-Driven Architecture (MDA) tools, and other XML processing technologies.
For more information about XML support, see the Language Reference Guide and the Workbench User Guide.
New XML System Classes
OpenROAD provides nine new classes for generating and parsing arbitrary XML files. No additional UserClasses or external classes are required. XML documents (URLs or files) are parsed into their tree-based object structure. The new system classes are:
XMLAttribute
Represents an attribute of an XML element—a name/value pair, which is part of an XML element start tag
XMLCDATA
Represents a CDATA section within an XML element. It is delimited by “<![CDATA[” and “]]>” tags in an XML document.
XMLComment
Represents a comment within an XML element. It is delimited by “<!--” and “-->” tags in an XML document.
XMLDocument
Reads and creates XML documents. It provides methods to create and parse XML documents. This class can represent an XML document in a tree-like object structure in memory. Additional low-level methods are provided to write documents without populating this object structure.
XMLElement
Represents an XML element, which is delimited by its starting and ending tags in an XML document
XMLNode
Represents a content part of an XML document
XMLPI
Represents a processing instruction within an XML element. It is delimited by the “<?” and “?>” tags within an XML document and has a target name different from “xml.”
XMLSchemaCache
Provides methods for adding and removing schemas to the cache, which can be used to validate XML documents
XMLText
Represents an untagged text part within an XML element
For complete information about these XML system classes, their attributes, and methods, see the Language Reference Guide and the System Reference Summary.
