Example of a string function

String functions are one of several XPath 2.0 functions supported in model expressions in IBM® Business Monitor. Define string XPath functions for use in monitor model XPath expressions.

The following code exemplifies the use of the string user-defined XPath function:

import com.ibm.wbimonitor.xml.expression.udf.XPathFunction;

public class Examples {
public static final String NAMESPACE = "http://www.jimbo.org/beverages/functions";

@XPathFunction(
namespaceName = NAMESPACE,
localName = "findAndReplace",
description = "(source, find, replace) Return the source string with all occurrences of find replaced with replace.",

isSelfContained = true,
isDeterministic = true
)
public static String findAndReplace(final String source, final String find, final String replace) {
return source.replace(find, replace);
}
}
