Getting custom element

Base on the sample journal xml content, if we want to get the localize ingress content. We can used liferay’s portal-kernel package such as SAXReaderUtil to parse the xml and get back the value. but we need to supply the locale.

  1.  
  2. Document document = SAXReaderUtil.read(article.getDefaultLocale());
  3. OR
  4. Document document = SAXReaderUtil.read(article.getContentByLocale(locale));
  5.  

Sample Code

  1.  
  2. import com.liferay.portal.kernel.xml.Document;
  3. import com.liferay.portal.kernel.xml.Node;
  4. import com.liferay.portal.kernel.xml.SAXReaderUtil;
  5. ………..
  6. private String getParseValue(String fieldname, JournalArticle article, String locale)
  7. {
  8.     String value = "";
  9.     try {
  10.          Document document =
  11.                        SAXReaderUtil.read(article.getContentByLocale(locale));
  12.          
  13.          Node node = document.selectSingleNode("/root/dynamic-element[@name='"
  14.                         + fieldname + "']/dynamic-content");
  15.  
  16.          value = node.getText();
  17.     }
  18.     catch(Exception e){
  19.        
  20.         if(log.isErrorEnabled()){
  21.               log.error(e.getMessage());
  22.         }
  23.     }
  24.  
  25.     return value;
  26. }
  27.  

DONE!
