The simple XQuery query retrieves all first names, middle names, last names, and education levels for all AdventureWorks job candidates. The XQuery path expressions in the example demonstrate some key XQuery concepts, including the following: The first item of note is the // axis at the beginning of each path expression. This axis notation is defined as shorthand for the descendant-or-self::node(), which I ll describe in more detail in the next section. This particular axis retrieves all nodes with a name matching the location step, regardless of where it occurs in the XML being queried. In the example, the four node tests specified are Name.First, Name.Middle, Name.Last, and Edu.Level. All nodes with the names that match the node tests are returned no matter where they occur in the XML. The * namespace qualifier is a wildcard that matches any namespace occurring in the XML. Each node in the result node sequence includes an xmlns namespace declaration. This XQuery query is composed of four different paths denoting the four different node sequences to be returned. They are separated from one another by commas.

Silverlight includes a standard TextBox control that supports many of the features of its counterpart in the Windows world, including scrolling, text wrapping, clipboard cut-and-paste, and selection. A text box always stores a string, which is provided by the Text property. You can change the alignment of that text using the TextAlignment property, and you can use all the properties listed in Table 5-2 to control the font of the text inside the text box. Ordinarily, the TextBox control stores a single line of text. (You can limit the allowed number of characters by setting the MaxLength property.) However, you can allow text to span multiple lines in two ways. First, you can enable wrapping using the TextWrapping property. Second, you can allow the user to insert line breaks with the Enter key by setting the AcceptsReturn property to True. Sometimes, you ll create a text box purely for the purpose of displaying text. In this case, set the IsReadOnly property to True to prevent editing. This is preferable to disabling the text box by setting IsEnabled to False because a disabled text box shows grayed-out text (which is more difficult to read) and does not support selection (or copying to the clipboard).

Summary

The location path determines which nodes should be accessed by XQuery. Following a location path from left to right is generally analogous to moving down and to the right in your XML node tree (there are exceptions, of course, which I discuss in the section on axis specifiers). If the first character of the path expression is a single forward slash (/), then the path expression is an absolute location path, meaning that it starts at the root of the XML. Listing 12-10 demonstrates the use of an XQuery absolute location path. The results are shown in Figure 12-11.

As you already know, you can select text in any text box by clicking and dragging with the mouse or holding down Shift while you move through the text with the arrow keys. The TextBox class also gives you the ability to determine or change the currently selected text programmatically, using the SelectionStart, SelectionLength, and SelectedText properties. SelectionStart identifies the zero-based position where the selection begins. For example, if you set this property to 10, the first selected character is the eleventh character in the text box. The Selection Length indicates the total number of selected characters. (A value of 0 indicates no selected characters.) Finally, the SelectedText property allows you to quickly examine or change the selected text in the text box. You can react to the selection being changed by handling the SelectionChanged event. Here s an example that reacts to this event and displays the current selection information: Private Sub txt_SelectionChanged(ByVal sender As Object, ByVal e As RoutedEventArgs) If txtSelection IsNot Nothing Then txtSelection.Text = String.Format("Selection from {0} to {1} is ""{2}""", _ txt.SelectionStart, txt.SelectionLength, txt.SelectedText) End If End Sub Figure 5-13 shows the result.
