extract values from xsd using xsl

[ozane]

Hi...
i am working on a web based tool. it is connecting to remote servers and receives a XSD as a response. what i need for next level is elements from xsd. here is the sample part of xsd

<xsd:element name="park" type="myns:park_Type" substitutionGroup="gml:_Feature"/>
	<xsd:complexType name="park_Type">
		<xsd:complexContent>
			<xsd:extension base="gml:AbstractFeatureType">
				<xsd:sequence>
					<xsd:element ref="gml:polygonProperty" minOccurs="0"/>
					<xsd:element name="AREA" type="string"/>
					<xsd:element name="PERIMETER" type="string"/>
					<xsd:element name="PARK_" type="string"/>
					<xsd:element name="PARK_ID" type="string"/>
					<xsd:element name="NAME_E" type="string"/>
					<xsd:element name="NAME_F" type="string"/>
					<xsd:element name="YEAR_EST" type="string"/>
					<xsd:element name="REG_CODE" type="string"/>
					<xsd:element name="AREA_KMSQ" type="string"/>
				</xsd:sequence>
			</xsd:extension>
		</xsd:complexContent>
	</xsd:complexType>

sometimes there are several elements in that xsd like above example.
i am trying to get those elements usign xslt. then those will populate different db tables.
how can i get that values from xsd with xslt?
for example i get the main elements like that

<xsl:for-each select="//xsd:element[@substitutionGroup='gml:_Feature']">
<xsl:value-of select="@name"></xsl:value-of>
,</xsl:for-each>

what about the other elements and their "name" attribute?
Thanks
