Hi,

if i'm understanding correctly you need to convert your String into an InputStream.

You can use the following code:

//convert String to InputStream
ByteArrayInputStream str = new ByteArrayInputStream(xml_file.getBytes());

after that you can use the following method to create a org.w3c.dom.Document object:

	public static Document generateXMLDocument(InputStream content)
	{
		try
		{
			// Create a builder factory
			InputSource inputSourceContent = new InputSource(content);
			DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
			factory.setValidating(false);
			Document doc = null;
			// Create the builder and parse the file
			//			Document doc = factory.newDocumentBuilder().parse(new File(filename));
			doc = factory.newDocumentBuilder().parse(content);

			return doc;
		}
		catch(DOMException domEx)
		{
			return null;
		}
		catch (SAXException e)
		{
			return null;
			// A parsing error occurred; the xml input is not valid
		}
		catch (ParserConfigurationException e)
		{
			return null;
		}
		catch (IOException e)
		{
			return null;
		}
		catch (Exception e)
		{
			return null;
		}

	}

Hope this help

If I understand correctly, your requirement is to write the xml string , to a file. You have two ways to do this.

1. With your own logic to ensure the well-formedness and correctness of xml in place, open a FileOutputStream and write the contents of the string. no xml business here...its plain file i/o.

2. Load your xml text into DOM and you can then refer this link for the sample code to do the rest

Hope this helps..
