我正在改写这个问题，希望它能更好地表达出来。我正在使用AJAX将字符串传递给此PHP脚本。 PHP脚本采用一串单词，将它们分成一个数组，然后尝试分析每个单词。我遇到的问题是，如果有一个单词无法分析，它就不会响应AJAX请求。如果一个单词无法分解，我希望它返回单词本身，但是它似乎跳过了这一行。
我也不知道如何将这个脚本制作成可以在自己的计算机上轻松测试的脚本，因为它有很多活动部件。我已经提取了相关的HTML，JS和PHP代码。让我知道是否还有其他帮助，或者无论如何我都可以澄清一下。
我是第一次使用PHP的Python程序员，但是调试起来很困难。

XML文件morphemes.xml包含如下条目：
<morpheme>
<source>hayu</source>
<gloss>dog</gloss>
</morpheme>
对于像hayunam xyz这样的字符串（第一个单词可以分解，而第二个单词不能分解），我希望它返回hayu -nam xyz
