    hi, fooling around with xmlspy (which seems pretty broken when *doing*
    xslt's). trying to validate in java using code from
    http://cermics.enpc.fr/doc/java/j2eetutorial-1.4/doc/JAXPSAX13.html
    (click on the Echo10.java link). i get an error saying that a doctype
    decl is required (see below). i get the same error whether or not i turn
    on name space awareness. spy says this file is well formed and valid.
    and my java code that transforms it with the same .xslt works as
    expected (all the files are at http://tayek.com/~ray/spy1/). the spy
    starts the xml doc that i am trying to validate with:

    <?xml version="1.0" encoding="UTF-8"?>
    <!--Sample XML file generated by XMLSPY v2004 rel. 3
    (http://www.xmlspy.com)-->
    <inputDocument xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:noNamespaceSchemaLocation="H:\java\projects\spy1\spy\inputDocument.xsd">
    <special>Text</special>
    <header>
    <inputFieldName>String</inputFieldName>

    while the .xsd file starts with:

    <?xml version="1.0" encoding="UTF-8"?>
    <!-- edited with XMLSPY v2004 rel. 3 U (http://www.xmlspy.com) by Ray
    Tayek (Freightgate) -->
    <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
    elementFormDefault="qualified" attributeFormDefault="unqualified">
    <xs:element name="inputDocument">
    <xs:annotation>
    <xs:documentation>input csv converted to xml</xs:documentation>
    </xs:annotation>

    what i would like to do is to validate the xml doc against it's schema
    before applying the transform (in java) . i have not yet tried the dom
    example at
    http://cermics.enpc.fr/doc/java/j2eetutorial-1.4/doc/JAXPDOM9.html as i
    thought the sax would be a bit more lightweight.

    i just started using spy (i had java code that does the transform just
    fine). but i used spy to generate the new .xsd and sample xml. so maybe
    he put some proprietary junk in there or something?

    anaict, doctype is for dtd's, but sax is complainig about a missing doctype.

    anybody got a clue?

    thanks


    output from Echo10.java when trying to validate the xml doc:
