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

FileReader readAsText returns some s

Answer 1

Here's a browser-based example, but this should be applicable to other JavaScript contexts:

Make a Form:

<div id="upload">
    <h2>Gimme Yo ODF Cornbread</h2>
    <form enctype="multipart/form-data" method="post">
        <input type="file" name="odfxml" id="odfxml" />
    </form>
</div>

Handle the Upload: (I'm using JQuery for brevity/simplicity)

<script>
    $("#odfxml").change(function(){
        var file = document.getElementById("odfxml").files[0];
                    //You could insert a check here to ensure proper file type
        var reader = new FileReader();
        reader.readAsText(file);
        reader.onloadend = function(){
            var xmlData = $(reader.result);
        };
    });
</script>

The xmldata variable contains your XML, ready for your magic.

Using the response like text:

var xml = data.replace(/[\s\S]+<\?xml/, '<?xml');
xml = xml.replace(/office:document\-meta>[\s\S]+/, 'office:document-meta>');

:)

If you need to load the xml like jquery object:

xml = $(xml);

then you can use jquery selector's on
