问题描述

我需要从 ODF 文件中获取 XML.我尝试使用 FileReader readAsText 和 readAsBinaryString 但它不起作用.

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

FileReader readAsText 返回 odf 文件的一些特殊字符.

FileReader readAsText returns some special characters for odf files.

使用 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);

如何使用 javascript FileReader 从 ODF 文件中获取 XML?

推荐答案

这是一个基于浏览器的示例，但这应该适用于其他 JavaScript 上下文:

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

制作表格:

<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>

处理上传:(为了简洁起见，我使用 JQuery)

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>

xmldata 变量包含您的 XML，为您的魔法做好准备.

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