[opencms-dev] xsd: defintion of attributes

[Shi Yusen]

Hi Nadine,

I think your requirement is possible in OpenCMS.

You can create a new resource type extended from xmlcontent and a new editor extended from xmlcontent editor, overlap the editor's reading and writing parts. When reading, parse the file from original xml format to a xmlcontent format. When writing, vice versa.

Good luck,

主题: [opencms-dev] xsd: defintion of attributes


Hi everybody, 

I´m trying to realize the following xml-file to be editable in OpenCms with 
structured content. Till now I worked with the examples in the documentation and everything was ok. 
I searched the mailing list but I found nothing similar. 
Besides I´ve  got the opinion that it is only possible to implement nothing execpt the given examples . 
The complex types for example seem not to be allowed to have more than the language attribute. 
When I try to define some further attributes to complex types of the xsd, I alwyas get errors. 

Has anybody succesfully written schema definitions for a xml file like that? 

        <?xml version="1.0" encoding="ISO-8859-1"?> 
        <Productinhalt Version="2.1.0" Name="Konfiguration"> 
                 <Product Key="02001"  Name="" ProductServer=""  ProductPort="52224" ProductPath=""> 
                  </Product> 
                 <Product Key="23001" Name="" ProductServer="" ProductPort="52224" ProductPath=""> 
                </Product> 
        </Productinhalt> 


My last working schema looked like this, but it is only possible with diffentent elements, not with several attributes. 

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified"> 
<xsd:include schemaLocation="opencms://opencms-xmlcontent.xsd"/> 
        <xsd:element name="Productinhalts" type="OpenCmsProductinhalts" /> 
        
        <xsd:complexType name="OpenCmsProductinhalts"> 
                <xsd:sequence> 
                        <xsd:element name="Productinhalt" type="OpenCmsProductinhalt" minOccurs="0" maxOccurs="unbounded"/> 
                </xsd:sequence> 
        </xsd:complexType> 

        <xsd:complexType name="OpenCmsProductinhalt"> 
                <xsd:sequence> 
                        <xsd:element name="Key" type="OpenCmsString" /> 
                        <xsd:element name="Name" type="OpenCmsString" /> 
                        <xsd:element name="ProductServer" type="OpenCmsString" /> 
                        <xsd:element name="ProductPort" type="OpenCmsString" /> 
                        <xsd:element name="ProductPath" type="OpenCmsString" /> 
                </xsd:sequence> 
                <xsd:attribute name="language" type="OpenCmsLocale" use="required" /> 
        </xsd:complexType>         
        
        <xsd:annotation> 
                <xsd:appinfo>                         
                        <resourcebundle name="de.inverso.vkb.vp.workplace"/> 
                        <mappings/> 
                        <defaults/> 
                        <layouts/> 
                </xsd:appinfo> 
        </xsd:annotation>   
 </xsd:schema> 


Result xml file: 

<?xml version="1.0" encoding="UTF-8"?> 
<Productinhalts xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="opencms://system/modules/de.inverso.vkb.vp/schemas/vp_content.xsd"> 
  <Productinhalt language="en"> 
    <Product> 
      <Key><![CDATA[02001]]></Key> 
      <Name/> 
      <ProductServer/> 
      <ProductPort><![CDATA[52224]]></ProductPort> 
      <ProductPath/> 
    </Product> 
    <Product> 
      <Key><![CDATA[23001]]></Key> 
      <Name/> 
      <ProductServer/> 
      <ProductPort><![CDATA[52224]]></ProductPort> 
      <ProductPath/> 
    </Product> 
  </Productinhalt> 
</Productinhalts> 


Thanks for your help!
