How to read XML file using FileReader javascript?

I need to get XML from a ODF file. I tried using FileReader readAsText and readAsBinaryString but its not working.

FileReader readAsText returns some special characters for odf files.

with readAsBinaryString

var reader = new FileReader()

reader.onloadend=function(e){

    var data = e.target.result;
    //data is not in xml format
    var xml = str2xml(data);
    //getting error
    /*
     using DOM parser for xml parsing
    */
}

reader.readAsBinaryString(file);

How can get XML from ODF file using javascript FileReader?

Webodf display odf from bytes

Is it possible for webodf to read a odf / odt file from its bytes? instead of an url?

Currently using:

var odfelement = document.getElementById("odf");
var odfcanvas = new odf.OdfCanvas(odfelement);

odfcanvas.load("url/to/file.odt");

and would like something like

odfcanvas.loadFromBytes(bytes);

Testing WebOdf Collaborative editor on localServer

I am trying to add document editor support in my website. I found Opensource WebODF and tried to test it on my local server. The git repository ReadMe gives instructions on how to add Odf viewer support. I was able to test the localeditor. Can some one explain how to setup the collaborative editor on local server.

Dynamically creating ODT using WebODF / Javascript

Using javascript, I need to create an .odt file and populate the contents with data in javascript variables. The only thing that I have found that might work is WebODF. An example that seems similar to it is here.

When I am trying to do something similar to PDF with pdfkit (using node) I can do something like this:

PDFDocument = require('pdfkit');
var doc = new PDFDocument();
doc.pipe(fs.createWriteStream(fileName));
doc.text("Fist line");
doc.text("Second line");

Is it possible to do something similar to it using WebODF? I've found ops.OpInsertText, but I'm not sure how I can use it to actually insert text.

Again, ideally the solution is only in javascript.

AJAX: Send file to Servlet and open response in new window

in my application, users can edit an ODF file via WebODF (http://webodf.org/). On save, i want to send the edited file to a servlet, have it convert to PDF via ODFDOM (http://code.google.com/p/xdocreport/wiki/ODFDOMConverterPDFViaIText) and open in a new window.

Currently i am trying to do this via AJAX. Everything works fine up to the point where i try to open the received PDF file.

My Javascript:

function showPDF(pServletUrl)
        {               
            var successCallback = function(pData)
            {
                var mimetype = "application/vnd.oasis.opendocument.text";
                var blob = new Blob([pData.buffer], {type: mimetype});
                var formData = new FormData();
                formData.append("file", blob, "test.odt");
                jQuery.ajax({
                    type: "POST", 
                    url: pServletUrl,
                    async: false, 
                    data: formData,
                    processData: false,
                    contentType: false, 
                    success: function(pSuccessData) 
                    { 
                        window.open(pSuccessData);
                    }, 
                    error: function(pErrorData) 
                    { 
                        console.log(pErrorData); 
                    }
                });
            }

            var errorCallback = function(data)
            {
                console.log(error);
            }

            _canvas.odfContainer().createByteArray(successCallback, errorCallback);
        }

My servlet:

public void handleRequest(HttpServletRequest pRequest, HttpServletResponse pResponse) throws ServletException, IOException
{
    BufferedInputStream tBufferedInput = null;
    BufferedOutputStream tBufferedOutput = null;

    try 
    {
        List<FileItem> tItems = new ServletFileUpload(new DiskFileItemFactory()).parseRequest(pRequest);
        for (FileItem tItem : tItems) 
        {
            if (!tItem.isFormField()) 
            {
                String tFieldname = tItem.getFieldName();
                String tFilename = FilenameUtils.getName(tItem.getName());
                InputStream tFilecontent = tItem.getInputStream();

                if("file".equals(tFieldname))
                {
                    tBufferedInput = new BufferedInputStream(tFilecontent);
                    pResponse.reset();
                    pResponse.setHeader("Content-Type", "application/pdf");
                    pResponse.setHeader("Content-Disposition", "inline; filename=\"" + "test.pdf" + "\"");
                    tBufferedOutput = new BufferedOutputStream(pResponse.getOutputStream(), 10240);

                    this.getOdtAsPdf(tBufferedInput, tBufferedOutput);

                    tBufferedOutput.flush();
                }
            }
        }
    }   
    catch(Exception e)
    {
        e.printStackTrace();
    }
    finally
    {
        try
        {
            tBufferedInput.close();
            tBufferedOutput.close();
        }
        catch(Exception e)
        {

        }
    }
}

private void getOdtAsPdf(InputStream pInputStream, OutputStream pOutputStream) throws Exception
{
    OdfDocument tOdfDocument = OdfDocument.loadDocument(pInputStream);
    PdfOptions tPdfOptions = PdfOptions.create();
    PdfConverter.getInstance().convert(tOdfDocument, pOutputStream, tPdfOptions);
}

It seems like Javascript wants to parse the recieved PDF file as a URL and (obviously) fails doing so. Is there a way to just open the file in a new window or do i have to find another way to do this?

Editing `ods` file in C++ code

I need to edit LibreOffice Calc document programmatically in C++. I know that there is odfkit library, which uses webodf, but it looks like it doesn't support editing .ods files.

Is there any alternative that can deliver me this feature?

Sample code on how to do ODF document rendering in webodf

I have some old program which we use to auto-generate table/curves etc. This program dumps LaTex. We are now moving to ODF standard instead of LaTex.

I am look for some examples on how to use webodf to render documents like table, section, reference, table of contents.

I have look at the API for webodf but I don't know where to start.

Can somebody show men some examples in ex. node.

Thank you
