XML Getting Started Tutorial: XLink-XML/XSLT analysis

XLink is a property-based syntax used to add links to XML documents. XLink links can be unidirectional, for example, element A in HTML. It can also be bidirectional. link two documents in two directions, therefore, it can be from A to B or from B to. Each XLink element must have an xlink: type attribute indicating the connection type. Attribute xlink: h XLink is a property-based syntax used to add links to XML documents. XLink links can be unidirectional, for example, element A in HTML. It can also be bidirectional. link two documents in two directions, therefore, it can be from A to B or from B to. Each XLink element must have an xlink: type attribute indicating the connection type. Property xlink: h

There are six types of xlink: type attributes:

simple，extended，locator，arc，title，resource。

The xlink: show attribute tells the browser or application what to do when activating the link. There are five possible actions:

• New. the link content is displayed in the new window.

• Replace: the link content is displayed in the current window.

• Embed: embedded content at the position of the current link element.

• Other: the action is uncertain and is specified by the application.

• None, no action.

• The xlink: actuate attribute tells the browser when to display the link. It has four possible values:

• OnLoad. Once a link is found, it is displayed immediately.

• OnRequest, which is displayed only when the user initiates a request.

• Other is determined by other marks in the document, rather than xlink.

• None, not specified.

• An example of the same effect as element A in HTML:

•     
       Jims
       
        2005/02/18
       
      

• An example of embedding an image on a page:

• Xlink: actuate and xlink: show are optional.

• The xlink: title and xlink: role attributes can be used to specify the description between resources. xlink: title contains a small amount of text describing remote resources. xlink: role contains the URI, which indicates a long description of the resource.
