Subject: [xsl] Simulate schema-awareness to create comboBoxes
Hello -
I need some advice, please. I have a multi-step problem and
am not sure the best direction to take. I've tried a few
different options, but surely someone has already solved this
more elegantly than what I am doing.... I am attending
<XML2006> and thought I could wait, but need to come up with
something before then...
Step 1: I need the global elements in a schema to be
represented as options in comboBoxes on a JSF page.
Step 2: I need to compare the user choices (in the instance
document) against the schema to dynamically add or remove
options from the comboBox according to the schema cardinality.
I can write a stylesheet to parse the schema to provide the
lists, but that just gives me a superset and doesn't account
for cardinality. And I would still have to continue to
compare the instance doc against the parsed schema to update
the comboBoxes as the user makes choices.
I'm using W3C XML Schema, XSLT 2.0, XPath 2.0 and Saxon8. We
have a license for SaxonSA, but it either doesn't offer the
type of functionality I need or I just didn't recognize it.
Schema:
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema";>
<xs:element name="root">
<xs:complexType>
<xs:sequence>
<xs:element ref="Item-A" minOccurs="0" maxOccurs="1" />
<xs:element ref="Item-B" minOccurs="1"
maxOccurs="unbounded" />
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:element name="Item-A" type="a-type"/>
<xs:element name="Item-B" type="b-type"/>
<xs:complexType name="a-type"/>
<xs:complexType name="b-type"/>
</xs:schema>
Instance 1 > Only option should be 'Item-B':
<?xml version="1.0" encoding="UTF-8"?>
<root>
<Item-A/>
</root>
Instance 2 > Options should be 'Item-A' and 'Item-B':
<?xml version="1.0" encoding="UTF-8"?>
<root>
<Item-B/>
</root>
If someone could point me in the right direction, I would
greatly appreciate it!
Thanks!
