XML and the SQL 2000 Server part 3: XML Data with XPath Queries - Xpath Query With a Template File

(Page 8 of 8 )

 

In Part 2, template files were discussed and how to use them for both SQL statements embedded in them, or for stored procedures. In a similar fashion, Xpath queries can be embedded in template files. These files are then placed in the template folder of the virtual directory. Once this is done, the Xpath queries can be executed by specifying the following in the URL:
http://IISServer/VirtualRoot/VirtualName/TemplateFile.xml
For the present setting of the virtual directory, the appropriate URL string is:
http://xphtek/Testpath/xtemplate/TestWizTempl.xml
The details of the TestWizTempl.xml template file is shown in the next picture:

Now the result of executing this query is shown in the next picture. If the mapping-schema file is not in the template folder, then an error will be generated. Note that the Xpath query must be enclosed by <SQL:xpath-query mapping-schema="xxx.xml"></sql:xpath-query>

This tutorial is Part 3 of the XML Data related tutorials and draws upon the information from Part 1 as it relates to setting up the Virtual directory and Part 2 as it relates to notions of URL queries and template queries.
