The following code example handles an HTML form that is
submitted as XML data. The content type value passed to the
processFormSubmission
method
is
CONTENT_TYPE=application/x-www-form-urlencoded
.The
values that correspond to the fields named
mortgageAmount
,
lastName
,
and
firstName
are displayed. A user-defined method
named
getNodeText
is used in this quick start.
It accepts an
org.w3c.dom.Document
instance and
a string value that specifies the node name. This method returns
a string value that represents the value of the node. (See Handling
Submitted Forms.)
