[opencms-dev] recursive element in schema

[Seckin Pulatkan]

Hi,

 

I am trying to create a schema for a type which may have itself as a
child element (recursive).

 

This is an xsd that can be used on OpenCMS that I can create element
with this xsd on workplace.

 

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

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified">

            <xsd:include
schemaLocation="opencms://opencms-xmlcontent.xsd"/>

            <xsd:element name="Chapters" type="OpenCmsChapters"/>

            <xsd:complexType name="OpenCmsChapters">

                        <xsd:sequence>

                                    <xsd:element name="Chapter"
type="OpenCmsChapter" minOccurs="0" maxOccurs="unbounded"/>

                        </xsd:sequence>

            </xsd:complexType>

            <xsd:complexType name="OpenCmsChapter">

                        <xsd:sequence>

                                    <xsd:element name="Title"
type="OpenCmsString" />

                                    <xsd:element name="Text"
type="OpenCmsHtml" minOccurs="0" />

                        </xsd:sequence>

                        <xsd:attribute name="language"
type="OpenCmsLocale" use="optional"/>

            </xsd:complexType>

            <xsd:annotation>

                        <xsd:appinfo>

                                    <resourcebundle
name="org.test.frontend.template.workplace"/>

                                    <mappings>

                                                <mapping element="Title"
mapto="property:Title" />

                                    </mappings>


                                    <layouts>

                                                <layout element="Text"
widget="HtmlWidget" configuration="height:100px" />

                                    </layouts>

                        </xsd:appinfo>

            </xsd:annotation>  

</xsd:schema>

 

 

A chapter may have sub-chapters of OpenCmsChapter type as in above
schema. So I add reference to the element Chapters

 

           <xsd:complexType name="OpenCmsChapter">

                        <xsd:sequence>

                                    <xsd:element name="Title"
type="OpenCmsString"/>

                                    <xsd:element name="Text"
type="OpenCmsHtml" minOccurs="0"/>

                                    <xsd:element ref="Chapters"
minOccurs="0" maxOccurs="unbounded"/>

                        </xsd:sequence>

                        <xsd:attribute name="language"
type="OpenCmsLocale" use="optional"/>

            </xsd:complexType>

or

 

<xsd:complexType name="OpenCmsChapter">

                        <xsd:sequence>

                                    <xsd:element name="Title"
type="OpenCmsString"/>

                                    <xsd:element name="Text"
type="OpenCmsHtml" minOccurs="0"/>

                                    <xsd:element name="SubChapters"
type="OpenCmsChapter" minOccurs="0" maxOccurs="unbounded"/>

                        </xsd:sequence>

                        <xsd:attribute name="language"
type="OpenCmsLocale" use="optional"/>

            </xsd:complexType>

 

Or 

 

<xsd:element name="SubChapter" type="OpenCmsChapter"/>

<xsd:complexType name="OpenCmsChapter">

                        <xsd:sequence>

                                    <xsd:element name="Title"
type="OpenCmsString"/>

                                    <xsd:element name="Text"
type="OpenCmsHtml" minOccurs="0"/>

                                    <xsd:element ref="SubChapter"
minOccurs="0" maxOccurs="unbounded"/>

                        </xsd:sequence>

                        <xsd:attribute name="language"
type="OpenCmsLocale" use="optional"/>

            </xsd:complexType>

 

But all changes get error from the workplace while creating a file with
this type.

 

First change: Invalid OpenCms content definition XML schema structure.

Second change: Invalid OpenCms content definition XML schema structure:
Schema type "OpenCmsChapter" unknown.

Third change: Invalid OpenCms content definition XML schema structure:
Exactly 1 root element is required, not
"opencms://opencms-xmlcontent.xsd".

 

Can you help me to figure out the problem? 

 

Thanks,

 

Seckin

 

Ps: Is there an official forum for OpenCms so I can check previous
questions before sending it again?
