Parsing an XSD to list elements
I have been trying to parse one(actually - many) xsd files to write out the list of element-names, respective element-type and documentation.
I looked into XSOM, SAXParser, Xerces, JAXP - all of which make it easy to read an xml and read nodes. Reading an xsd without equating to element names (to get a list of all element names) seems difficult. The parser.parse works fine with most of the libs I tried (as an XSD is a well formed xml), but I am not able to get beyond that (to extract all element names).
Am I missing anything? Anyone has any experience with a similar problem?
following is a sample xsd:
<?xml version="1.0" encoding="utf-8" ?>
<xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns="http://abc.mycompany.com/dto/address" targetNamespace="http://abc.mycompany.com/sdo/address">
<xs:complexType name="Address">
<xs:sequence>
<xs:element name="address1" minOccurs="0">
<xs:annotation>
<xs:documentation>USPS standardized address: building number, street name, apartment/suite number, and directionals (e.g., NE, SE, NW, SW).</xs:documentation>
</xs:annotation>
<xs:simpleType>
<xs:restriction base="xs:normalizedString">
<xs:maxLength value="100" />
</xs:restriction>
</xs:simpleType>
</xs:element>
<xs:element name="address2" minOccurs="0">
<xs:annotation>
<xs:documentation>Additional field for wrapping long addresses.</xs:documentation>
</xs:annotation>
<xs:simpleType>

</xs:restriction>
</xs:simpleType>
</xs:element>
<xs:element name="city" minOccurs="0">
<xs:annotation>
<xs:documentation>Name of the city, town or village.</xs:documentation>
</xs:annotation>
<xs:simpleType>
<xs:restriction base="xs:normalizedString">
<xs:maxLength value="26" />
</xs:restriction>
</xs:simpleType>
</xs:element>
<xs:element name="state" type="xs:normalizedString" minOccurs="0" >
<xs:annotation>
<xs:documentation>A pick list of two-letter abbreviations representing US states,
military post offices, US protectorates, and Canadian provinces.
</xs:documentation>
</xs:annotation>
</xs:element>
<xs:element name="zipCode" type="xs:normalizedString" minOccurs="0" >
<xs:annotation>
<xs:documentation>The first 5 digits of a 9-digit (Zip+4) zip code,
used to geographically locate a US address.</xs:documentation>
</xs:annotation>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:schema>
It's gotta be a parser that's configured to deal with the namespace.
You could also use XSL-T to match on "xs:element" and extract the names that way.
