Hi Peter,
I have upgraded my project from Cocoon 2.1.8 to 2.1.9. It did not bring
in any extra whitespace behaviour.
The saveDocument() function from 2.1.9 samples could be responsible
although I doubt. I use a modified version of it. Hereafter the code you
may try to see if it makes any difference. (Please note this code is
test code).
importPackage(Packages.java.io);
importPackage(Packages.javax.xml.transform);
/* document: DOM document to be saved
* uri: Path to saved file /tmp/mydoc.xml
* encoding: For ex: "ISO-8859-1"
*/
function saveDocument(document, uri, encoding) {
cocoon.log.info("saveDocument, uri: " + uri);
var outFile = null;
var bufferOS = null;
try {
outFile = new Packages.java.io.File(uri);
var fileOS = new FileOutputStream(outFile);
var bufferOS = new BufferedOutputStream(fileOS);
var resultStream = new
Packages.javax.xml.transform.stream.StreamResult(bufferOS);
var factory = TransformerFactory.newInstance();
var transformer = factory.newTransformer();
transformer.setOutputProperty(OutputKeys.INDENT, "false");
transformer.setOutputProperty(OutputKeys.METHOD, "xml");
transformer.setOutputProperty(OutputKeys.ENCODING, encoding);
transformer.setOutputProperty(
OutputKeys.OMIT_XML_DECLARATION, "no");
transformer.transform(
new Packages.javax.xml.transform.dom.DOMSource(document),
resultStream
);
cocoon.log.info(
"saveDocument() trans. from document to resultStream done");
}
catch (error) {
cocoon.log.error("saveDocument(): Could not save document: " +
error);
}
finally {
if (bufferOS != null) {
try {
bufferOS.flush();
bufferOS.close();
} catch (error) {
cocoon.log.error(
"Could not flush/close BufferedOutputStream: " +
error);
}
}
}
}
The third cause for extra whitespace might come from your binding...

Hi Patrick,
I am using Cocoon 2.1.9. I am doing the following
//All the ***URI variables are in putted via the sitemap
//create new form
var form = new Form(definitionURI);
// bind form - builds the binding using xslt via the sitemap
form.createBinding('cocoon:/'+bindingURI);
// parse the xml document, which is to be amended to a DOM-tree
var document = loadDocument(documentURI);
// bind the document data to the form
form.load(document);
// show the form to the user until it is validated successfully
form.showForm(documentURI+"lodge-display-pipeline"); // bind the
form's data back to the document
form.save(document);
// save the DOM-tree back to an XML file using the saveDocument function
from the CForm samples
saveDocument(document, documentURI);

Hi,
I am using CForms to amend an xml file on the server. Every time the
file is amended it gets a lot of extra whitespace, when it is saved
using the flowscript, wherever there is a repeater widget.
Please how can I stop this happening

Hi Peter,
I think you should give more details about what you mean by "saved
using the flowscript". I am not aware of a single way to saving an XML
file representation in flowscript (DOM) to a file.
I do use Cocoon Flow with DOM binding to amend XML files, using
repeaters, and did not notice the behaviour you describe. (Using
Cocoon 2.1.8)
