java.lang.Object | +--weblogic.apache.xalan.lib.Extensions
This class contains many of the Xalan-supplied extensions. It is accessed by specifying a namespace URI as follows:
xmlns:xalan="http://xml.apache.org/xalan"
This class is based on an implementation from the Apache XML Project. In future releases the XML parser, XSLT processor, and associated classes will likely be updated to be based on a later version of the Apache implementations. Since Apache does not guarantee backwards compatibility between versions of their software, we cannot guarantee backwards compatibility of any of the classes contained in the weblogic.apache package or sub-packages.

Method Detail |
public static NodeSet nodeset(ExpressionContext myProcessor, java.lang.Object rtf)
nodeset
returns a node-set consisting of a single root node as described in
section 11.1 of the XSLT 1.0 Recommendation. If the argument is a
node-set, nodeset
returns a node-set. If the argument
is a string, number, or boolean, then nodeset
returns
a node-set consisting of a single root node with a single text node
child that is the result of calling the XPath string() function on the
passed parameter. If the argument is anything else, then a node-set
is returned consisting of a single root node with a single text node
child that is the result of calling the java toString()
method on the passed argument.
Most of the
actual work here is done in MethodResolver
and
XRTreeFrag
.

If the first argument is an empty string or contains only delimiters, the result
will be an empty NodeSet.

Simply calls the EnvironmentCheck
utility to grab info about the Java environment and CLASSPATH,
etc., and then returns the resulting Node. Stylesheets can
then maniuplate this data or simply xsl:copy-of the Node.
We throw a WrappedRuntimeException in the unlikely case that reading information from the environment throws us an exception. (Is this really the best thing to do?)
