[opencms-dev] (no subject) - retrieve xml content manually

[Peter Birchmeier]

Thanx, i didn't know that method. But after looking through its source code, 
i think its rather a slow way to retrieve xml content since the xml file 
must be unmarshalled for eaxh element...

I tried to find a way with as less code as possible, which is still fast 
enough.


something like that might do the job:

import org.opencms.jsp.*, org.opencms.main.*, import org.opencms.file.*, 
org.opencms.file.collectors.*, import org.opencms.xml.*, 
org.opencms.xml.content.*;

CmsJspActionElement cms = ..

I_CmsResourceCollector collector = 
OpenCms.getResourceManager().getContentCollector(m_collectorName);
List collectorResult = collector.getResults(cms.getObject(), 
m_collectorName, m_collectorParam);

CmsResource resource = (CmsResource) collectorResult.get( 0..n );

public String getContent( CmsResource resource, String element, Locale 
locale) {
	CmsFile file = CmsFile.upgrade( resource, cms.getCmsObject() );
	I_CmsXmlDocument content = CmsXmlContentFactory.unmarshal( 
cms.getCmsObject(), file );

	Locale loc = OpenCms.getLocaleManager().getBestMatchingLocale( locale,
		OpenCms.getLocaleManager().getDefaultLocales(cms, 
cms.getSitePath(resource)),
		content.getLocales(element));

	return content.getStringValue( element, loc );
}

hmmm.. i'm not sure if it is a good idea to use too much code..
maybe anybody has a better idea? The most practical way would be if 
xmlcontentload-tags could be used together with scriptlets that request a 
specific xml content element from the loaded xml file...
