In the life cycle of XML documents there are instances when the XML structure needs to be changed to accommodate various needs. For example, when an associated schema is updated, an attribute may have been removed, or a new element added to the structure.
These types of situations cannot be resolved with a traditional Find/Replace tool, even if the tool accepts regular expressions. The problem becomes even more complicated if an XML document is computed or referenced from multiple modules, since multiple resources need to be changed.
To assist you with these types of refactoring tasks, Oxygen XML Author Eclipse plugin includes a specialized XML Refactoring tool that helps you manage the structure of your XML documents.
XML Refactoring Tool
The XML Refactoring tool is presented in the form of an easy to use wizard that is designed to reduce the time and effort required to perform various structure management tasks. For example, you can insert, delete, or rename an attribute in all instances of a particular element that is found in all documents within your project.
XML Refactoring action from one of the following
locations:- The XML menu.
- The Refactoring submenu from the contextual menu in the Project Explorer view.
- The Refactoring submenu from the contextual menu in the DITA Maps Manager view.
XML Refactoring Wizard
- Refactoring operations
-
The first wizard page presents the available operations, grouped by category. To search for an operation, you can use the filter text box at the top of the page.

- Configure Operation Parameters
-
The next wizard page allows you to specify the parameters for the refactoring operation. The parameters are specific to the type of refactoring operation that is being performed. For example, to delete an attribute you need to specify the parent element and the qualified name of the attribute to be removed.

- Scope and Filters
-
The last wizard page allows you to select the set of files that represent the input of the operation.
Figure 3. XML Refactoring - Scope and Filters Wizard Page
- Scope section
- You can specify the scope for the operation by selecting from predefined resource sets or you can define your own set of resources by creating a working set (select Working sets and click the Choose button to the right). If you select Project, all files attached to the current project will be used for the scope of the operation. If you select Current DITA Map hierarchy, the current DITA map that is open in the DITA Maps Manager along with all of its referenced topics and submaps (and topics referenced in those submaps) are used for the scope.
- Filters
- The Filters section includes the following
options:
- Include files - Allows you to filter the selected resources by using a file pattern. For example, to restrict the operation to only analyze build files you could use build*.xml for the file pattern.
- Restrict only to known XML file types - When selected, only resources with a known XML file type will be affected by the operation.
- Preview
- You can use the Preview button to open a comparison panel where you can review all the changes that will be made by the refactoring operation before applying the changes.
- Finish
- After clicking the Finish button, the operation will be processed and Oxygen XML Author Eclipse plugin provides no automatic means for reverting the operations. Any Undo action will only revert changes on the current document.
Stop button in the progress bar to cancel the operation.
