Recently I saw a lot of articles introducing XML from the Internet, when the XML file is output, the sample code is:
...
// output XML document to the specified file FileOutputStream outStream = new FileOutputStream (outFile); OutputStreamWriter outWriter = new OutputStreamWriter (outStream); ((org.apache.crimson.tree.XmlDocument) doc) .write (outWriter, "GB2312" Outwriter.close (); outstream.close ();
...
Unfortunately, this code can not pass ... will appear CASS CAST EXCEPTION Error!
The author seems to have not realized.
After my research, I proposed a solution. Use Transformer to output an XML file. Complete code
Public Static Void CallWriteXmlFile (Document Doc, Writer W, String Encoding) {Try {// Prepare The Dom Document for Writing Source Source = New Domsource (DOC);
// prepare the output file result result = new streamResult (w);
// Write the DOM document to the file Transformer xformer = TransformerFactory.newInstance () .newTransformer (); xformer.setOutputProperty (OutputKeys.ENCODING, encoding); xformer.transform (source, result);
} Catch (TransformerConfigurationException E) {E.PrintStackTrace ();} catch (transformerExcection e) {E.PrintStackTrace ();}}
After I compiled in WinXP, JDK1.4, the package to include is:
Import javax.xml.parsers. *; // XML parser interface import org.w3c.dom. *; // XML DOM implementation
Import javax.xml.transform. *; import javax.xml.transform.dom.domsource; import javax.xml.transform.stream.streamResult;
Correspondingly, the error of the error should be corrected:
// The XML document output to the specified file FileOutputStream outStream = new FileOutputStream (outFile); OutputStreamWriter outWriter = new (outStream) OutputStreamWriter; // error class cast exception // ((org.apache.crimson.tree.XmlDocument) doc ) .write (Outwriter, "GB2312"); // exchange additional output XML method CallWriteXMLFile (DOC, OUTWRITER, "GB2312"); outstream.close (); outstream.close (); Outstream.close ();
and so,
