This custom XPath function is built into MashZone NextGen. To use the function in an XPath expression you must:

1. Declare the MashZone NextGen custom XPath namespace on <mashup> in your mashup script. For example:

2. Define the to and from formats for the date or time you need to convert.

For example:

These formats use patterns to identify the various date or timecomponents. Some of the most common include:

Pattern	Usage
dd	Day of the month such as 05.
yyyy	Year.
MM	Numerical month.
MMM	Text month
hh	Hour in a 12-hour format (1-12).
HH	Hour in a 24-hour format (0-23).
a	AM/PM for 12-hour time formats.
mm	Minute
ss	Second
S	Millisecond

The complete list of characters and symbols that are valid inpatterns are defined in the java.text.SimpleDateFormat class. For detailedinformation, see Java API documentation for the JDK version used in yourenvironment.

3. Use the function in an XPath expression. In most cases you would use this function along with an XPath constructor function to obtain a date or time.
