Multistep Location Paths

• The forward slash (/) combines location steps into a location path.

• The node-set selected by the first step becomes the context node-set for the second step. The node-set identified by the second step becomes the context node-set for the third step, and so on.

Examples

• child::PERIODIC_TABLE/child::ATOM is an XPath expression that selects all ATOM elements.

• child::PERIODIC_TABLE/child::ATOM[1] is an XPath expression that selects the first ATOM element.

• child::PERIODIC_TABLE/child::ATOM/child::SYMBOL is an XPath expression that selects all SYMBOL elements.

• child::PERIODIC_TABLE/child::ATOM[ATOMIC_NUMBER="3"] is an XPath expression that selects Lithium.

• child::ATOM[SYMBOL="He"]/child::DENSITY/attribute::UNITS is an XPath expression that selects the units in which the density of Helium is given.

• child::PERIODIC_TABLE/child::ATOM/child::* is an XPath expression that selects all the child elements of ATOM elements.
