- <!-- This transformer is used to extract the form instance data from the xml document. See
- the javadocs of this class for more information on the default configuration and
- configuration options.
- The instance data is stored as an attribute with the same name as the form using an
- output module. Here we decide to use the RequestAttributeMap module. This would allows
- a) to store instances for several forms and b) to access a particular instance and value
- using JXPath syntax.
- Per default, the map key is the name of the form as is the root node of the new Document.

- from an input module attribute with the same name. In addition, it checks the result
- of the FormValidatorAction when it encounters <error/> tags and includes / excludes
- them depending on the result.
-
- While many configuration options are available at run time, the input module has
- to be configured at declaration time. Thus a second instance of the SimpleFormTransformer
- is needed.
-
- How is the instance data accessed?
- If the user submitted data, those parameters shall be used, otherwise,
- it is stored as Document (DOM) in a Map that is stored in a request attribute.
- Thus, first a request attribute is read, passing a fixed attribute name because the name
- of the map is fixed. This is the default name for attributes set by the RequestAttributeMap
- module.
- Next, a JXPath expression is applied to this map. The expression is the name attribute of the
- HTML form tag currently transformed! Since both map key and root node is the same (here: "person"),
- and we don't want to reflect this in our HTML form, the simplemap input module is used to
- prepend the string "/person/" to the jxpath expression.

<group name="Simple Form Handling">
<note>
This samples group demonstrates the use for the simple form handling
in Apache Cocoon. Simple form handling consists of four parts:
validating user input, filling forms with submitted data, displaying
validation results, and filling forms with default values. This
corresponds largely to the involved Cocoon components: a validating
action, a logicsheet helping to display validation results, a
transformer to fill in submitted data and display validation results,
and a transformer to extract default values.
</note>
<note>
Apache Cocoon contains several approaches to forms. The one demonstrated
here is probably the simplest but also the weakest. Please do consider
the others as well: JXForms and Woody.
</note>
<sample name="Logicsheet" href="one/index">
On a XSP two logicsheets are used to redisplay submitted data and
indicate validation results.
</sample>
<sample name="One Transformer" href="two/index">
On a static XML page a form is displayed, submitted data is filled in,
and validation results are displayed by the use of the
SimpleFormTransformer.
</sample>
<sample name="Default Values" href="three/index">
On a static XML page, form elements are separated from the default
values. The SimpleFormInstanceTransformer is used to extract the data
and the SimpleFormTransformer is used to pre-fill the form. No
validation is performed.
