[opencms-dev] how to update xml values within a CmsFile

[Steve Bryan]

Hi Frank

There may be a better way, in which case I would like to hear - but
otherwise you can extract the dom4j Document, and work with that directly -
you would need to look at the API doc for Dom4j if you are not familiar with
it.

eg
CmsXmlContent content = CmsXmlContentFactory.unmarshal(cmsObject, file);
String sContent = content.toString();
Document doc = CmsXmlUtils.unmarshalHelper(sContent, null);

// Work with doc...

String sNewContent = CmsXmlUtils.marshal(doc, CmsEncoder.ENCODING_UTF_8);

					
// Save the contents
file.setContents(sNewContent.getBytes());
cmsObject.writeFile(file);

Hi,
 
Given certain conditions, I'm trying to update an xml value within a CmsFile
programmatically.  I've gotten to a point where I've been able to unmarshal
the file and can retrieve the value, but am looking for some direction on
how to update this value.  Any help would be appreciated.
 
This is what I have so far:
 
CmsFile resourceFile = CmsFile.upgrade(cr, cms);CmsXmlContent xmlDocument =
CmsXmlContentFactory.unmarshal(cms, resourceFile, true);Locale locale = new
Locale(cms.getRequestContext().getLocale().toString());String value =
xmlDocument.getStringValue(cms, "Section/ABC", locale);
 
// if value is true, then update the value
if ("true".equals(value)) {
     // ???
 
}
 
Thanks so much in advance!
 
Frank
