The code above uses three tags from the XPath tag library: getvalue , ifdef , and iterate . All three tags have a select attribute that specifies an XPath expression.
The getvalue applies the XPath expression specified in the select , on the Order DOM document instance and substitutes the result.
The conditional ifdef tag evaluates its body content only if the XPath expressions specified in its select are valid.
iterate , an iteration tag, parses its body contents for each iteration. In this case, the select attribute specifies a node set to be retrieved which is then iterated over. Note that the getvalue tag, when used within the iterate tag, specifies a relative XPath expression in its select attribute.
The example above covers simple data access, substitution, and control flow using XPath expressions in a JSP. The next example discusses attribute value substitution.
Example 2: Attribute value substitution
In our second example, the JSP uses XPath expressions to access the ShipTo data from the DOM instance, which is then edited using an HTML form. Note the use of the template: prefix for attribute value substitution:
editShipTo.jsp
<%@ taglib uri="/src/tags/taglib.tld" prefix="mytag" %>
