Help designing an XSD

Post by **aevarga** » Sun Feb 11, 2007 2:00 am

I am looking for help in creating an XSD definition for a paragraph of text with font changes in the middle. The original example is from W3Schools, but I want to highlight a word in mid-sentence.

Here is the XML:

Code: Select all


<?xml version="1.0"?>



<note

xmlns="http://www.w3schools.com"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://www.w3schools.com note.xsd">



<to>Tove</to>

<from>Jani</from>

<heading>Reminder</heading>

<body>Don't forget me <underline>this</underline> weekend!</body>

</note>

And here is the original XSD::

Code: Select all


<?xml version="1.0"?>

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"

targetNamespace="http://www.w3schools.com"

xmlns="http://www.w3schools.com"

elementFormDefault="qualified"><xs:element name="note">

   <xs:complexType>

     <xs:sequence>

   <xs:element name="to" type="xs:string"/>

   <xs:element name="from" type="xs:string"/>

   <xs:element name="heading" type="xs:string"/>

   <xs:element name="body" type="xs:string"/>

     </xs:sequence>

   </xs:complexType>

</xs:element></xs:schema>

My problem is trying to figure out how to define the <underline> element within the <body> element, because the <body> element already has text inside it. I'm sure it's simple, but I haven't been able to find any examples of where someone has already done this.

Thanks in advance for any help.

Hello,

You have to allow both text content and the underline element inside the body element. For example you can use the following schema:

Code: Select all

<?xml version="1.0" encoding="UTF-8"?>

<xs:schema elementFormDefault="qualified" targetNamespace="http://www.w3schools.com"

    xmlns="http://www.w3schools.com" xmlns:xs="http://www.w3.org/2001/XMLSchema">

    <xs:element name="note">

        <xs:complexType>

            <xs:sequence>

                <xs:element name="to" type="xs:string"/>

                <xs:element name="from" type="xs:string"/>

                <xs:element name="heading" type="xs:string"/>

                <xs:element name="body">

                    <xs:complexType mixed="true">

                        <xs:sequence minOccurs="0" maxOccurs="unbounded">

                            <xs:element name="underline" type="xs:string"/>

                        </xs:sequence>

                    </xs:complexType>

                </xs:element>

            </xs:sequence>

        </xs:complexType>

    </xs:element>

</xs:schema>

Regards,
Sorin

It looks like the part I was missing was

xs:complexType mixed="true"

That worked when I integrated it into my more complicated scheme (not the sample here). Thanks very much!
