在XUL JavaScript中执行XSLT转换文件时出现问题

我正在研究XUL，并尝试使用JavaScript在XUL中执行XSLT处理器函数

我有一个JavaScript函数，可以将新记录更新到XML文件并保存XML文件。之后，我尝试执行XSLT处理器函数，但无法加载XSL和XML文件

function xslt()
{
var processor = new XSLTProcessor();

var testTransform = document.implementation.createDocument("", "test", null);
// just an example to get a transform into a script as a DOM
// XMLDocument.load is asynchronous, so all processing happens in the
// onload handler
testTransform.addEventListener("load", onload, false);
testTransform.load("file://C:/mercredi.xml");
function onload() {
  processor.importStylesheet(testTransform);
}
}

我的工作环境是在windows中使用Eclipse、XulBooster。通常，要加载任何文件，我使用file://C:/mercredi.xml或C:/mercredi.xml；这两个文件路径在其他函数中都可以正常工作，甚至在JavaScript函数中也是如此，我使用了相同的文件路径来读取和保存XML文件

function xslt()
{
var processor = new XSLTProcessor();

var testTransform = document.implementation.createDocument("", "test", null);
// just an example to get a transform into a script as a DOM
// XMLDocument.load is asynchronous, so all processing happens in the
// onload handler
testTransform.addEventListener("load", onload, false);
testTransform.load("file://C:/mercredi.xml");
function onload() {
  processor.importStylesheet(testTransform);
}
}

1.我已从本网站复制了以下代码列表6：

然后我查看了Mozilla网站并按照说明进行操作，但仍然无法加载我的文件。 2.以下代码复制自本网站：

即使在这个函数中，我也无法加载XML文件

function xslt()
{
var processor = new XSLTProcessor();

var testTransform = document.implementation.createDocument("", "test", null);
// just an example to get a transform into a script as a DOM
// XMLDocument.load is asynchronous, so all processing happens in the
// onload handler
testTransform.addEventListener("load", onload, false);
testTransform.load("file://C:/mercredi.xml");
function onload() {
  processor.importStylesheet(testTransform);
}
}

这是我的JavaScript代码，用于执行XSLT处理器的处理函数

function saveFile(output, savefile) {

    //function from http://puna.net.nz/archives/Code/Mozilla%20XUL%20LOG%20-%20read%20local%20files%20and%20write%20local%20files.htm
    //var savefile = "c:\\mozdata.txt";

    try {
        netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");
    } catch (e) {
        alert("Permission to save file was denied.");
    }
    var file = Components.classes["@mozilla.org/file/local;1"]
        .createInstance(Components.interfaces.nsILocalFile);
    file.initWithPath( savefile );
    if ( file.exists() == false ) {
        alert( "File Updated Successfully ");
        file.create( Components.interfaces.nsIFile.NORMAL_FILE_TYPE, 420 );
    }
    var outputStream = Components.classes["@mozilla.org/network/file-output-stream;1"]
        .createInstance( Components.interfaces.nsIFileOutputStream );
    /* Open flags
    #define PR_RDONLY       0x01

    */
    outputStream.init( file, 0x04 | 0x08 | 0x20, 420, 0 );
    var result = outputStream.write( output, output.length );
    outputStream.close();
alert( "File Updated Successfully ");
clear();
process();

}

为什么要在XUL中执行XSLT文件？是在XML文件中为我的客户生成唯一的ID

function xslt()
{
var processor = new XSLTProcessor();

var testTransform = document.implementation.createDocument("", "test", null);
// just an example to get a transform into a script as a DOM
// XMLDocument.load is asynchronous, so all processing happens in the
// onload handler
testTransform.addEventListener("load", onload, false);
testTransform.load("file://C:/mercredi.xml");
function onload() {
  processor.importStylesheet(testTransform);
}
}

请帮帮我我做错了什么？！？多谢各位

这是我的XSLT文件：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output method="xml" indent="yes"/>
    <xsl:strip-space elements="*"/>

    <xsl:template match="node()|@*">
        <xsl:copy>
            <xsl:apply-templates select="node()|@*"/>
        </xsl:copy>
    </xsl:template>

    <xsl:template match="CONTACT">
        <xsl:copy>
               <Customer-Id>
               <xsl:value-of select="generate-id(.)"/> 
               </Customer-Id>
              <xsl:copy-of select="FirstName|LastName|gmail|yahoo| Hotmail |URL|Facebook-ID"/>
        </xsl:copy>
    </xsl:template>

</xsl:stylesheet>

出于某种原因：

var testTransform = document.implementation.createDocument("", "test", null);

及

它不起作用

然后我意识到我在JavaScript中使用“readFile函数”来加载文件。我使用这个函数加载XUL中的任何文件

代码如下：

function process()
{ 
    var src = readFile("c:\\idgenerator.xsl");//load my XSl file
    var parsed = (new DOMParser()).parseFromString(src, "text/xml");
    var stylesheet = parsed.documentElement;
    var processor = new XSLTProcessor();
    processor.importStylesheet(stylesheet );

    objXMLDoc = processor.transformToDocument(objXMLDoc);//load & transform my XML file

    var serializer = new XMLSerializer();
    var prettyString = serializer.serializeToString(objXMLDoc);
    saveFile(prettyString, "C:\\mercredi.xml");//Save the XML file
}

你忘了说你到底犯了什么错误。提示：逐字粘贴错误消息将有助于其他人以后找到此帖子不幸的是，错误控制台中没有关于此问题的错误消息。@karthik:即使没有错误消息，您仍然可以告诉我们您看到的确切症状。你怎么知道代码不起作用？预期的行为是什么，实际的行为是什么？@Larsh:我已经用警报消息验证过了。警报'1'；transform.loadfile://C:/idgenerator.xsl；警报2'；警报1起作用，但警报2不起作用。我的代码在transform.load停止工作@拉尔斯：我已经解决了这个问题。请告诉我如何发布解决方案？
