在 XUL JavaScript 中使用 XSLT 处理器的多个 XSL 文件

我有 4 个 XSl 文件，如果我在 Firefox XUL 中使用 XSLT 处理器一一执行，这些文件可以完美运行。当我同时一一执行所有 XSL 文件时，它不会生成最终输出。
如果我逐个使用 XSL 文件，这就是上述 XML 文件的实际输出：
<?xml version="1.0" encoding="UTF-8"?>

这是在 XUL 中调用 XSl 文件的实际 JS 函数：
function process()
{
var src = readFile("D:\\createXML2.xsl");
var parsed = (new DOMParser()).parseFromString(src, "text/xml");
var stylesheet = parsed.documentElement;
var processor = new XSLTProcessor();
processor.importStylesheet(stylesheet );
objXMLDoc = processor.transformToDocument(objXMLDoc);
var serializer = new XMLSerializer();
var prettyString = serializer.serializeToString(objXMLDoc);
saveFile(prettyString, "D:\\aout30.xml");
//alert('New Contact updated successfully');
var prompts = Components.classes["@mozilla.org/embedcomp/prompt-service;1"]
.getService(Components.interfaces.nsIPromptService);
prompts.alert(null, "Final creation", "Final creation is done");
process2();
}
这些是我用来生成最终输出的 XSL 文件：
File1：合并具有相同 FN & 的联系人LN
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes"/>
<xsl:key name="groupName" match="//CONTACTS/CONTACT" use="concat(FirstName, LastName)" />
<xsl:template match="CONTACTS">

<xsl:sort select="CONTACT/EMail" />

文件 3：文件 3 根据域类型分隔电子邮件值

substring-after(.,'@'),

</Type>
<Value><xsl:value-of select="."/></Value>
</EMail>
</xsl:template>
</xsl:stylesheet>
文件 4：为每个联系人生成客户 ID，并将电子邮件域标签添加到生成的第 3 个 xsl 的电子邮件值类型输出文件。
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

有时它会生成正确的输出，但大多数时候它不起作用。 我真的不明白可能是什么问题。是否有可能将所有这些 SL 文件合并为一个文件？请帮我。谢谢。

I have 4 XSl files which is working perfectly if I execute one by one using XSLT processor in Firefox XUL. When I execute all the XSL files one by one simultaneously it's not generating the final output.
This the actual output of the above XML file if I use the XSL files one by one:
<?xml version="1.0" encoding="UTF-8"?>

This is the actual JS function to call the XSl file in XUL:
function process()
{
var src = readFile("D:\\createXML2.xsl");
var parsed = (new DOMParser()).parseFromString(src, "text/xml");
var stylesheet = parsed.documentElement;
var processor = new XSLTProcessor();
processor.importStylesheet(stylesheet );
objXMLDoc = processor.transformToDocument(objXMLDoc);
var serializer = new XMLSerializer();
var prettyString = serializer.serializeToString(objXMLDoc);
saveFile(prettyString, "D:\\aout30.xml");
//alert('New Contact updated successfully');
var prompts = Components.classes["@mozilla.org/embedcomp/prompt-service;1"]
.getService(Components.interfaces.nsIPromptService);
prompts.alert(null, "Final creation", "Final creation is done");
process2();
}
These are the XSL files I'm using to generate my final output:

Sometimes it's generating the proper output but most of the time it's not working.
I really don't understand what could be the problem. Is there any possibility to combine all these SL files as a single file? Please help me. Thank you.

要组合上面显示的转换，您需要一个
node-set()扩展函数，您的 javascript 库可能无法提供该函数（是吗？）。但是，至少对于上面显示的输入示例（稍作更改以涵盖其他情况），我认为可以通过单个转换来执行所有任务。
请注意，当 URL 节点位于重复的 CONTACT 中时，您的解决方案（以及此解决方案）不会处理 Facebook-ID 生成的元素。
当应用于以下输入时：
产生：
To combine the transforms shown above you would need a
node-set()extension function, which is probably not available from your javascript library (is it?).However, at least for the input sample shown above (slightly changed to cover other cases), I think it is possible to perform all of your tasks with a single transform.
Note your solution (and this one too) does not handle Facebook-ID generated element when URL node is in the duplicate CONTACT.
When applied on the following input:
