The first two articles briefly describe the method for parsing xml by using sax to implement the parsing function. The following uses sax to create an xml file. The first two articles briefly describe the method for parsing xml by using sax to implement the parsing function. The following uses sax to create an xml file.

The specific method of using sax to create xml is to add relevant comments to the program, or directly add the code.


Package cn.com. sax; import java. io. outputStream; import java. io. stringWriter; import javax. xml. transform. outputKeys; import javax. xml. transform. result; import javax. xml. transform. transformer; import javax. xml. transform. transformerConfigurationException; import javax. xml. transform. sax. SAXTransformerFactory; import javax. xml. transform. sax. transformerHandler; import javax. xml. transform. stream. streamResult; impo Rt org. xml. sax. SAXException; import org. xml. sax. helpers. attributesImpl; import android. util. log; class SxaCreateXml {/*** generate an XML *** @ param list * @ return */public String saxToXml (OutputStream output) {String xmlStr = null; try {// used to generate an XML file // The Object implementing this interface contains the information required to build the conversion Result tree Result resultXml = new StreamResult (output ); // used to obtain the XML string format // A response stream, which can be used to collect the output in the string buffer to construct the string StringWriter writerStr = new StringWriter (); // Information required to build the conversion result tree. Result resultStr = new StreamResult (writerStr); // Create a SAX conversion factory SAXTransformerFactory sff = (SAXTransformerFactory) SAXTransformerFactory. newInstance (); // The conversion processor that listens to the SAX ContentHandler // parses events and converts them to the result tree ResultTransformerHandler th = sff. newTransformerHandler (); // Convert the source tree to the result tree Transformer transformer = th. getTransformer (); // sets the character encoding transformer. setOutputProperty (OutputKeys. ENCODING, "UTF-8"); // whether to indent transformer. setOutputProperty (OutputKeys. INDENT, "yes"); // sets the Result associated with the TransformerHandler used for conversion. // Note: The two th. setResult cannot be enabled at the same time. setResult (resultXml); // th. setResult (resultStr); // create the root element
 
  
And set its property to null th. startDocument (); AttributesImpl attr = new AttributesImpl (); th. startElement ("", "calsses", "calsses", attr); // creates a level-1 subelement.
  
   
And set its attributes to attr. clear (); attr. addAttribute ("", "name", "name", "", ""); attr. addAttribute ("", "num", "num", "", "10"); th. startElement ("", "", "group", attr); // creates a level-2 subelement.
   
    
And set its attributes to attr. clear (); attr. addAttribute ("", "name", "name", "", "James"); attr. addAttribute ("", "age", "age", "", "7"); th. startElement ("", "", "person", attr); // create a third-level sub-element
    
     
And set its value to attr. clear (); th. startElement ("", "", "chinese", attr); th. characters ("90 90 ". toCharArray (), 0, "90 ". length (); th. endElement ("", "", "chinese"); // creates a level 3 subelement.
     
      
And set its value th. startElement ("", "", "english", attr); th. characters ("English 80 ". toCharArray (), 0, "English 80 ". length (); th. endElement ("", "", "english"); th. endElement ("", "", "person"); th. endElement ("", "", "group"); th. endElement ("", "calsses", "calsses"); th. endDocument (); xmlStr = writerStr. getBuffer (). toString ();} catch (TransformerConfigurationException e) {Log. e ("TEST", "" + e. toString ();} catch (SAXException e) {Log. e ("TEST", "" + e. toString ();} catch (Exception e) {Log. e ("TEST", "" + e. toString ();} Log. e ("TEST", "generated" + xmlStr); return xmlStr ;}}
     
    
   
  
 


You can call this method to create an xml file.


new SxaCreateXml().saxToXml(openFileOutput("sax.xml",  Context.MODE_PRIVATE));


The generated sax. xml file is still in the data/cn. xxx. xxx/files folder.
