The xml data type also provides the .exist() method, which accepts a path expression and returns 1 if the query returns any nodes, and alternatively returns 0 if the query doesn t return any nodes. Consider listing 6, which tells you whether the word dimensions appears in the character data of any of the <definition> elements in the XML data. This sample relies on the sample data used in listing 4. Results are shown in figure 5.

set myContact to make new contact with properties {first name:"Estelle", last name:"Kalamand", nickname:"Stella", title:"Dr", business phone number:"510-555-8280"} tell myContact set the business web page to "http://wwwacmevirtualindustriescom" set the mobile phone number to "707-555-1083" set the job title to "Executive Director" set the age to 35 set the children to {"Max (2005)", "Anne (2008)"} set the astrology sign to "Sagitto-Gemini Dragon" end tell

SELECT CASE @x.exist ( N'/definitions/concept/definition[contains(., "dimensions")]' ) WHEN 1 THEN N'The word "dimensions" exists in a definition' WHEN 0 THEN N'The word "dimensions" doesn''t exist in a definition' END;

These days, most of your contacts will have multiple e-mail addresses, so you ll want to load those addresses into the contact records in Entourage and tell the application which e-mail address to use as the default As you may have noticed in Table 16-11, the contact object has a property called default email address, but it doesn t have different e-mail address properties like it has properties for phone numbers the home phone number property, the other home phone number property, the mobile phone number property, and so on This is because Entourage stores the e-mail addresses in email address objects and then makes the default one available through the contact s default email address property

Listing 6 introduces a new XQuery function, contains(), which works similarly to (but not exactly like) the SQL Server CHARINDEX() function to determine whether a given string is contained within your data. The full list of XQuery functions and operators (often referred to with the abbreviation F &O) available to SQL Server XQuery is available in Books Online at http://msdn.microsoft.com/en-us/library/ms189254.aspx.

In this example, we used a different predicate that uses the XQuery contains function. This function accepts a node and a string value. In this example, we used the period character (.), which indicates the current context node. The predicate returns true for every node that matches the predicate criteria. In this case, every node that contains the word dimensions returns true. The contains function (like XML in general, and by extension XQuery) is case sensitive. The .exist() method is most commonly used in the WHERE clause of SQL statements. The .nodes() method allows you to shred your XML data or convert it into relational form. This method accepts a path expression and returns a relational result set of matching nodes as an xml data type column. The .nodes() method requires you to alias the result set and column name that will be returned. In listing 7, we used the alias Result for the returned result set and Col for the single xml data type column in that set. Again, this sample relies on the XML data introduced in listing 4. Partial results are shown in figure 6.

If you ve added various e-mail addresses manually to a contact record in Entourage, you ll see how this works On the Name & E-mail tab of the Contact Properties window (see Figure 16-3), you add addresses to the E-mail list box Entourage gives the first address you add the label Work, but you can change it to Home or Other as needed Once you ve added two or more addresses, you can click one of them and then click the Make Default button to make it the default e-mail address for the contact The default e-mail address appears in boldface so that you can easily pick it out From AppleScript, you add e-mail addresses to Entourage contacts in the same way

SELECT Col.value(N'(./name)[1]', N'nvarchar(100)') AS [Name], Col.value(N'(./definition)[1]', N'nvarchar(1000)') AS [Definition] FROM @x.nodes(N'//concept') Result(Col);

First, add the e-mail addresses to the contact as email address objects, using the label property to specify the label (work, home, or other) and the contents property to give the e-mail address Then set the default email address property to the appropriate email address object
