Hi guys, sorry to be asking this here. But I'm having trouble googling this
out.
Here is the problem. Given an xml document. I read it on my app and
manipulate it, then save it when I am done.
When I remove a child, the output files shows all the extra lines from the
formatting and indent. So it looks like a big hole in the xml file after the
node is removed. Here is an example
<bookshelf>
<books>
<book>
<isbn>3349583080580584308</isbn>
<author>Jon Stewart</author>
</book>
<book>
<isbn>9900909770543356488</isbn>
<author>Stephen Colbert</author>
</book>
</books>
</bookshelf>
Node parentNode = jonStewartNode.getParentNode();
parentNode.removeChild (jonStewartNode);
The result of this is the following xml.
<bookshelf>
<books>
<book>
<isbn>9900909770543356488< /isbn>
<author>Stephen Colbert</author>
</book>
</books>
</bookshelf>
How can I output the xml without this extra lines?
Thanks in advance,
f(t)
PS: here is the initialization, and configuration of the TransformerFactory,
and Transformer, and finally the save method.
/**
* Initializes factory instances and member variables.
*/
private void initialize(){
try{
//obtain a trasformer factory to save the file
this.transformerFactory = TransformerFactory.newInstance();
this.transformerFactory.setAttribute("indent-number", 4);
//obtain the transforme
this.transformer = this.transformerFactory.newTransformer();
//setup transformer
this.transformer.setOutputProperty(OutputKeys.METHOD, "xml");
this.transformer.setOutputProperty(OutputKeys.INDENT, "yes");
//this.transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount
<http://xml.apache.org/xslt%7Dindent-amount>", "4");
}catch(TransformerConfigurationException tcex){
this.logger.logException(this, "
errors.storage.xml.configuringXmlTransformer", true, tcex);
}
}
/**
* Saves the DOM document to the XML file.
*/
private void saveDocument(){
//verify that the documents is not null
if(this.document==null)
return;
//sincronize document
synchronized (this.document){
try{
//normalize document
this.document.normalizeDocument();
//get a document documentSource object out of the document
DOMSource documentSource = new DOMSource(
this.document);
//create the file output stream
FileOutputStream fileOutputStream = new
FileOutputStream( this.file);
//create the output stream writer
OutputStreamWriter outputStreamWriter = new
OutputStreamWriter(fileOutputStream);
//create the stream streamResult out to the file Stream
StreamResult streamResult = new
StreamResult(outputStreamWriter);
//performe the trasformation
transformer.transform(documentSource, streamResult);
//clean up
outputStreamWriter.close();
outputStreamWriter = null;
fileOutputStream.close();
fileOutputStream = null;
documentSource = null;
} catch (TransformerConfigurationException tcex) {
// Error generated by the parser
// Log Error
this.logger.logException(this, "
errors.storage.xml.saveXMLRepositoryFile", true, tcex);
} catch (TransformerException tex) {
// Error generated by the parser
// Log Error
this.logger.logException(this, "
errors.storage.xml.saveXMLRepositoryFile", true, tex);
} catch (Exception ex) {
// Unknown error
// Log Error
this.logger.logException(this, "
errors.storage.xml.saveXMLRepositoryFile", true, ex);
}
}
}
