Summary

Today, you took a look at three XML specifications: XLink, XPointer, and XForms. All three of these XML applications were taken over from HTML into XML by the W3C.

You use XLinks to create hyperlinks in XML. You've seen that any XML element can be an XLink; all you have to do is use the correct attributes. The one required attribute, xlink:type, sets the type of XLink; possible values are "simple", "extended", "locator", "arc", "resource", "title", and "none".

Simple XLinks are very much like HTML hyperlinks. To create them, you just set the xlink:href and xlink:type attributes. Extended XLinks can get quite complex, however, as you've seen today. Today you talked about inline and out-of-line XLinks in extended links, and you created extended links that included arcs, or directional links, by using the xlink:from and xlink:to attributes.

XPointers let us narrow down searches—down to specific elements or even specific characters in text. The XPointer specification is now divided into three recommendations—the XPointer framework, the element scheme, and the namespace scheme—along with the working draft for the general XPointer scheme. The W3C created this division to make XPointers easier to implement.

Today we talked about how to use the XPointer framework to use element names—barenames—as XPointers; the element scheme to identify elements by ID; and the namespace scheme to use namespaces in XPointers.

The general XPointer scheme is where the full power of XPointers lies, even though there are very few implementations of this scheme yet. General XPointers are powerful because they support full XPath expressions, as well as two more data types—points and ranges.

XForms are the XML analog of HTML Web forms, and you use them to display controls such as buttons and select controls. Today you saw that one of the major ideas behind XForms is to separate data from presentation, and, accordingly, XForms store their data in an XForms model, typically in an XHTML document's <head> section. The presentation of the actual controls the XForm displays is done with specialized elements such as <input> and <select>.

Tomorrow you'll start working with XML and JavaScript.

Q&A

Q1:

How can I declare XLink elements and attributes to make my documents valid?

A1:

Here's an example, which declares a simple XLink element, <link>, in a DTD:

<!ELEMENT link>
<!ATTLIST link
    xmlns:xlink CDATA #FIXED "http://www.w3.org/1999/xlink"
    xlink:type CDATA #FIXED "simple"
    xlink:href CDATA #REQUIRED
    xlink:show (new | replace | embed | none | other) #IMPLIED "replace">
Q2:

An XForm input control handles only a single line of text. What can I use if I want to display multiple lines of text?

A2:

You can use the XForms <textarea> element to display multiple lines of text. Here's an example:

<xforms:textarea ref="/data/textarea">
    <xforms:label>Textarea</xforms:label>
</xforms:textarea>
