Home > Online Product Documentation > Table of Contents > Source Documents Source DocumentsIn Stylus Studio, a source document in the XSLT mapper can be an XML document, an XML Schema (XSD), or a document type definition (DTD). The role of a source document is to provide Stylus Studio with a structure that it can use to compose the XSLT stylesheet, based on how you map individual source document elements and attributes to nodes in the target structure. Stylus Studio infers the target structure from the document (XML, XSD, or DTD) you specify and displays this structure on the Mapper tab. In this sectionThis section covers the following topics: Choosing Source DocumentsYou can use one or more source documents to build a stylesheet in the Stylus Studio XSLT mapper. You might want to select more than one document if you need their elements or attributes to fully describe the target structure or the desired XSLT result content, or if you want to aggregate multiple sources in a single document, for example.
If you choose an XSD or DTD document, you must also choose an XML instance document to associate with it. Stylus Studio uses the instance document associated with an XSD or DTD source document to generate the XPath
For more informationSee Source Documents and XML Instances to learn more about how Stylus Studio treats source documents. See Creating an XSLT Scenario to learn more about XSLT scenarios. Source Documents and XML InstancesAs described previously, Stylus Studio uses the source documents you specify to display a structure you can use to create mappings to the target structure. In addition to the document structure, Stylus Studio needs document content information in order to compose a correct XSLT stylesheet. You provide this information by associating a XML instance to each source document you specify. Types of associationsSource documents can have one of three associations, each of which has implications for the XPath expressions written by Stylus Studio, which uses these documents when it composes the XSLT stylesheet. A source document can be associated with
By default, Stylus Studio uses the first XML document you add to the XSLT mapper as the source XML for the XSLT scenario, as shown here: The document specified in the Source XML URL field on the Scenario Properties dialog box is the document to which the XSLT is applied when you preview the XSLT. You can select this association for another XML document if you choose, but only one source document may have this association.
Source document iconsStylus Studio uses different document icons to indicate how a source document structure is related to corresponding XML document content.
How to change a source document associationTo change a source document association:
1. Click the
Mapper tab if necessary.
2. Right click the source document whose association you want to change.
The source document shortcut menu appears.
3. Click
Associate With, and then select the document you want to associate with the source document.
How to Add a Source DocumentTo add a source document to XSLT mapper:
1. Click the
Mapper tab if necessary.
2. Click the
Add Source Document button at the top left of the
Mapper tab.
The Open dialog box appears.
3. Select the document you want to use as the source document to map to the target document.
4. Click
Open.
If you selected an XML document in step 3, the document appears in the source document pane of the Mapper tab. Go to step 5. If you selected an XSD or DTD document, Stylus Studio displays the Choose Root Element dialog box.
You use the Associate With field to associate the XSD or DTD with an XML instance.
a. Select the element from the XSD or DTD document that you want to use as the root element. The
Choose root element drop-down list displays elements defined in the document you selected in
step 3.
b. Use the
Browse (
) button to specify the XML instance to which you want to associate the document you have chosen as your structure. The root element of the XML document you select should be the same as the element you selected as the root element from the XSD or DTD document.
c. Click
OK.
The document appears in the source document pane of the Mapper tab. Go to step 5.
5. To add another source document, return to
step 2.
How to Remove a Source Document
To remove a source document from the XSLT mapper:
1. Click the
Mapper tab if necessary.
2. Remove any maps from the source document to the target schema. (See
Removing Source-Target Maps if you need help with this step.)
3. Right click on the source document.
The source document shortcut menu appears.
4. Select
Remove Schema.
How Source Documents are DisplayedA source document is represented in the mapper using a document icon; its name is displayed using a different color to help distinguish the document from elements and attributes. The document icon is modified based on the source document's association with other documents. See Source Documents and XML Instances for more information on this topic. By default, only the file name itself is displayed; if you want, you can display the document's full path by selecting Show Full Path on the document's shortcut menu. (Right-click on the document name to display the shortcut menu.)
Source documents are displayed using the tree view; you can use your standard keyboard's *, +, and - number pad keys to expand and collapse selected documents. Document structure symbolsStylus Studio uses the following symbols to represent nodes in both source and target document structures
See Source document icons to learn about the different ways source document icons are depicted. Getting source document detailsIf you want details about the source document that are not available in tree view, you can open the document by selecting Open from the document's shortcut menu. When you open a document this way, Stylus Studio displays it in the XML editor. XSD and DTD documents are displayed on the XML editor's Schema tab. |
