cvc-complex-type.2.4.a: Invalid content was found

[peridian]

I must be going blind or dumb, because for the life of me I cannot see why I would get this error:

cvc-complex-type.2.4.a: Invalid content was found starting with element 'config'. One of '{config}' is expected.

With the following files:

XSD:

<?xml version="1.0"?>
<xs:schema
    targetNamespace="http://tempuri.org/Page"
    xmlns="http://tempuri.org/Page"
    xmlns:xs="http://www.w3.org/2001/XMLSchema">
 
    <xs:element name="template">
        <xs:complexType>
            <xs:sequence>
                <xs:element name="config" type="configuration" minOccurs="1" maxOccurs="1" />
            </xs:sequence>
        </xs:complexType>
    </xs:element>
 
    <xs:complexType name="configuration">
        <xs:sequence>
            <xs:element name="root" type="xs:string" minOccurs="1" maxOccurs="1" />
        </xs:sequence>
    </xs:complexType>
 
</xs:schema>
 

XML:

<?xml version="1.0" encoding="UTF-8"?>
<template
    xmlns="http://tempuri.org/Page"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://tempuri.org/Page ../template.xsd">
   <config>
      <root>somevalue</root>
   </config>
 
</template>
 

Eclipse seems to be okay with the file reference, as the intellisense does correctly give me the tag names as expected, allows me to enter the data then gives me this error.

Any ideas?

Okay,

I appear to have solved the problem, though I don't understand it. I fed the same setup into a different XML editor, and its intellisense did something I did not expect. It added a BLANK XML namespace to the <config> tag:

<?xml version="1.0" encoding="UTF-8"?>
<template
    xmlns="http://tempuri.org/Page"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://tempuri.org/Page ../template.xsd">
   <config xmlns="">
      <root>somevalue</root>
   </config>
 
</template>
 

I could not understand why, when the page has already been assigned a default namespace. Tried it back in Eclipse and it worked. The obvious next thing to do was to remove the default namespace:

<?xml version="1.0" encoding="UTF-8"?>
<template
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://tempuri.org/Page ../template.xsd">
   <config>
      <root>somevalue</root>
   </config>
 
</template>
 

This now works correctly, although Eclipse throws up warnings about no namespace for the document being declared (thankfully you can turn those off).

It appears that specifying a default xmlns attribute at the root of the document is mutually exclusive with using the xsi:schemaLocation approach. I was puzzled by this as I have had it work when the XML and XSD are in the same location:

<?xml version="1.0" encoding="UTF-8"?>
<template xmlns="http://tempuri.org/Page">
   <config>
      <root>somevalue</root>
   </config>
</template>
 

As long as the two files are in the same physical location, all the XML editors I have used correctly identify and validate the schema. As soon as the files are in different locations, I seem to need the xsi:schemaLocation method, which then causes conflicts with the default namespace attribute.

If anybody can shed any light on what is going on here, it would be appreciated.

Rob.

you should put "elementFormDefault='qualified' " in your xml schema. For more information, you can search for "elementFormDefault". I am poor at English so I cannot interpret the document for you. Good luck. I am trapped in this too.
