XSLT, 2nd Edition

Name

[2.0] static-base-uri()

Returns the value of the base URI property from the static context. The base URI property can change from one XML element to the next, but static-base-uri() returns the same value regardless of the location in the input document. In Saxon-J 9.0.0.3, the static base URI is the base URI of the stylesheet. Altova XML works similarly, although the format of the URI is not exactly the same.

Syntax

xs:anyURI? static-base-uri()

Inputs

None.

Outputs

An xs:anyURI that represents the static base URI. If the base URI property is not defined in the static context, static-base-uri() returns the empty sequence.

Defined in

XQuery 1.0 and XPath 2.0 Functions and Operators section 16, “Context Functions.”

Example

To illustrate how static-base-uri() works, we’ll reuse our earlier document that used the xml:base attribute to define different base URIs throughout the document:

<?xml version="1.0" encoding="utf-8"?>
<!-- xmlbase.xml -->
<cars>
  <manufacturer name="Chevrolet"
    xml:base="http://www.chevrolet.com/">
    <car>Cavalier</car>
    <car>Corvette</car>
    <car>Impala</car>
    <car>Malibu</car>
  </manufacturer>
  <manufacturer name="Ford"
    xml:base="http://www.ford.com/">
    <car>Pinto</car>
    <car>Mustang</car>
    <car>Taurus</car>
  </manufacturer>
  <manufacturer name="Volkswagen"
    xml:base="http://www.vw.com/">
    <car>Beetle</car>
    <car>Jetta</car>
    <car>Passat</car>
    <car>Touraeg</car>
  </manufacturer>
</cars>

Here’s our stylesheet. We call the static-base-uri() function at the document root, and we also call ...
