The default regex based validation for XML contents can be replaced by a custom validation since OpenCms 6.0. In order to do that, you need to specify your own XML content handler class in the XSD like this:
<xsd:annotation>
<xsd:appinfo>
<handler class="my.own.XmlContentHandlerImplementationClassNameGoesHere" />
... Other nodes as required ...
</xsd:appinfo>
</xsd:annotation>A handler needs to implement the org.opencms.xml.content.I_CmsXmlContentHandler interface.
In case you need only special validation, it's a good idea to extend the default content handler and override only the required method, like this:
public class XmlContentHandlerImplementationClassNameGoesHere extends org.opencms.xml.content.CmsDefaultXmlContentHandler { public XmlContentHandlerImplementationClassNameGoesHere() { super(); } public CmsXmlContentErrorHandler resolveValidation( CmsObject cms, I_CmsXmlContentValue value, CmsXmlContentErrorHandler errorHandler) { if (errorHandler == null) { // init a new error handler if required errorHandler = new CmsXmlContentErrorHandler(); } if (value.getName().equals("NameOfTheXmlNodeIAmInterestedIn")) { if ("BadValue".equals(value.getStringValue(cms))) { errorHandler.addError(value, "The interesting node has a bad value!"); } } else { errorHandler = super.resolveValidation(cms, value, errorHandler); } // return the result return errorHandler; } }
