Hi Geert,
The platform where I am working is based on X* and I have very limited options
to use Java or any other language...except XSLT.
I did look at Trang, looks promising.. but that could an option if nothing else
works out.
thank you
Densil

Subject: Re: [xsl] reg XSD generation using XSL
why would you want to do that with XSLT?
use trang for a first stab at it
http://www.thaiopensource.com/relaxng/trang.html
you can develop some XSLT logic to twiddle the output of that to your
convenience
be prepared to do some manual stuff as well

Hi all, My previous posts didnt get thru the list..as I was not yet on the
mailing list.. hence I am posting it here. I am wondering if anyone had
attempted to generate an schema from an input XML document. I am kind of stuck
up in this and I am wondering if could get some help here. The Schemas has to
be
ver 1.0 and generation code has to be written using XSL. I worked out a basic
idea.. like 1) Open schema tag and check for name spaces 2) Check if current
context is root, 2.1) is context root:- Print the element name.
2.1.1) if children and attributes are present, the context is complex...else
print context (single tag) as simple 2.1.2) If complex, print
child
element names based on their types 2.1.2.1) check if the
children are complex in a for each loop and then goto 2.1.1 2.2.1)
close the complex tag..and check for attributes. 3) close the doc with /schema
I
came up with a basic code and it is working for xml with one root element and
first children. If it goes towards grand children, I am kind of printing out
same element types twice or more as they are visible in previous siblings. I
am
wondering what could be a generic solution here. e.g. inbound xml <?xml
version='1.0' encoding="UTF-8"?> <catalog cat="music"> <cd country="RSA">
<title>Empire Burlesque</title> <artist>Bob Dylan</artist>
<price>10.90</price> </cd> <dd county="UK"> <title1>Hide your
heart 4</title1> <artist1>Bonnie Tyler</artist1>
<price2>9.90</price2> </dd> <dc county="UK"> <title2>Hide your
heart 4</title2> <artist2>Bonnie Tyler</artist2>
<price2>9.90</price2> </dc> </catalog> The schema results in <xs:schema
xmlns:xs="http://www.w3.org/2001/XMLSchema"; elementFormDefault="qualified"
attributeFormDefault="unqualified"> <xs:element name="catalog">
<xs:complexType> <xs:sequence> <xs:element name="cd"
type="cdType"/> <xs:element name="dd" type="ddType"/>
<xs:element name="dc" type="dcType"/> </xs:sequence>
</xs:complexType> </xs:element> <xs:complexType name="cdType">
<xs:sequence> <xs:element name="title" type="titleType"/>
<xs:element name="artist" type="artistType"/> <xs:element
name="price" type="priceType"/> </xs:sequence> <xs:attribute
name="country" type="xs:string"/> </xs:complexType> <xs:simpleType
name="titleType"> <xs:restriction base="xs:string"/>
</xs:simpleType> <xs:simpleType name="artistType"> <xs:restriction
base="xs:string"/> </xs:simpleType> <xs:simpleType name="priceType">
<xs:restriction base="xs:integer"/> </xs:simpleType>
<xs:complexType name="ddType"> <xs:sequence> <xs:element
name="title1" type="title1Type"/> <xs:element name="artist1"
type="artist1Type"/> <xs:element name="price2" type="price2Type"/>
</xs:sequence> <xs:attribute name="county" type="xs:string"/>
</xs:complexType> <xs:simpleType name="title1Type">
<xs:restriction
base="xs:string"/> </xs:simpleType> <xs:simpleType name="artist1Type">
<xs:restriction base="xs:string"/> </xs:simpleType>
<xs:simpleType name="price2Type"> <xs:restriction base="xs:integer"/>
</xs:simpleType> <xs:complexType name="dcType"> <xs:sequence>
<xs:element name="title2" type="title2Type"/> <xs:element
name="artist2" type="artist2Type"/> <xs:element name="price2"
type="price2Type"/> </xs:sequence> <xs:attribute name="county"
type="xs:string"/> </xs:complexType> <xs:simpleType name="title2Type">
<xs:restriction base="xs:string"/> </xs:simpleType>
<xs:simpleType name="artist2Type"> <xs:restriction base="xs:string"/>
</xs:simpleType> <xs:simpleType name="price2Type"> <xs:restriction
base="xs:integer"/> </xs:simpleType> </xs:schema> where the simple type
price2Type is repeated twice once processing dd and then dc. as I am
processing
only the children of that node context. I am wondering what could be a
generic
solution here to avoid duplicates at this context node. thankyou Densil
