XPath over XML Schema: Examples
Contents
Sample XSD used in examples Boilerplate
Examples: 1, 2, 3, 4, 5, 6 (more examples in the download).
Example 6: /ex:Collection/ex:Deliveries/ex:Delivery/ex:Address/ex:City
/**
* In this example we will first select a node, and then we will write
* another XPath which selects all ancestors of this node.
*/

Output
- First XPath: /ex:Collection/ex:Deliveries/ex:Delivery/ex:Address/ex:City
Matched nodes:
/Collection[1,1](50:3)/Deliveries[1,1](54:7)/Delivery[0,inf](46:7)/Address[1,1](29:7)/City[1,1](16:7)
- Second XPath: ancestor::ex:*
Matched nodes:
/Collection[1,1](50:3)/Deliveries[1,1](54:7)/Delivery[0,inf](46:7)/Address[1,1](29:7)
/Collection[1,1](50:3)/Deliveries[1,1](54:7)/Delivery[0,inf](46:7)
/Collection[1,1](50:3)/Deliveries[1,1](54:7)
/Collection[1,1](50:3)
