Validation in IE never fails!

[Andrew]

Hi

I'm new to this group, so apologies if it's an old chestnut, or not
appropriate to this group....

I have been playing around with creating xml files and schemas with
which to validate them. In order to validate them, I've downloaded the
"Tools for validating XML and viewing XSL output" from Microsoft and
installed them. I've tried this on various machines, with various
browser versions and OS's.

However, when the file is valid, right-clicking --> Validate XML
reports "Validation Successful". But then introducing deliberate (and
quite major) errors still results in "Validation Successful".

As an example:

staff.xml

<staff xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="staff.xsd" >
<person>
<name>Andrew Richards</name>
<dept>Training</dept>
</person>
</staff>


This will validate as is - even if the named xsd file doesn't exist!
But, I then create this:

staff.xsd

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<xsd:element name="name" type="xsd:string"/>
<xsd:element name="dept" type="xsd:string"/>
<xsd:element name="person">
<xsd:complexType>
<xsd:sequence>
<xsd:element ref="name"/>
<xsd:element ref="dept"/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
<xsd:element name="staff">
<xsd:complexType>
<xsd:sequence>
<xsd:element ref="person"/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:schema>

And as expected, the xml file once again validates successfully.

But if I "break" the schema - perhaps by changing the element
declaration for "dept" to "Department", it STILL validates!!!

Am I doing something wrong? Or is IE unable to validate against
schemas? And if so, what's the best way of validating an XML file?


Thanks for your help

It sounds like if IE was validating only regarding DTDs, not schema

Perhaps you should use a more suitable tool for validating ; the MSXMLn
suite contains various classes for that purpose ; Java has also numbers
of tools

I would recommend using a standalone validating parser.
xmllint is great, but:

- I like small tools. YMMV.
- I've no idea if there's a native Windows port. If there
isn't one, you can always install Cygwin with libxml2
package.

Even if xmllint doesn't work for you, there's a number of
software packages that come with similar functionality,
both command line and GUI. Ask Google for details.

IE supports validating against a DTD. If you want to validate against a
schema (or multiple schemas) then you need to install and use MSXML 6
and script the validation.
MSXML 6 is available for download here

I always thought that xmllint was a small tool:

ldd `which xmllint`
libxml2.so.2 => /usr/lib/libxml2.so.2 (0x00979000)
libpthread.so.0 => /lib/tls/libpthread.so.0 (0x00dcd000)
libz.so.1 => /usr/lib/libz.so.1 (0x00dab000)
libm.so.6 => /lib/tls/libm.so.6 (0x00d80000)
libc.so.6 => /lib/tls/libc.so.6 (0x00101000)
/lib/ld-linux.so.2 (0x005a2000)
ll `which xmllint`
-rwxr-xr-x 1 root root 50250 Oct 26 2005 /usr/bin/xmllint*

If that aint small enough, then maybe xmlwf is:

ldd `which xmlwf`
libexpat.so.0 => /usr/lib/libexpat.so.0 (0x00369000)
libc.so.6 => /lib/tls/libc.so.6 (0x00101000)
/lib/ld-linux.so.2 (0x005a2000)
ll `which xmlwf`
-rwxr-xr-x 1 root root 21828 Oct 24 2005 /usr/bin/xmlwf*

-rwxr-xr-x 1 root root 50250 Oct 26 2005 /usr/bin/xmllint*

That's why I like it. Not everyone has a soft spot for
small tools, however, and for people like that xmllint
might not be the best option. That's what my warning was
about.
