如何使用AppleScript获取和解析XML文件？

某个远程服务器上有一个XML文件(http://foo/bar.xml):

酒吧

如何使用AppleScript获取值“bar”？

我发现它有一个示例，可以通过系统事件使用XML工具解析XML文件。但对我来说似乎很复杂

还有这个（免费软件）用于解析/编写XML。我没看过，但它可能很整洁

就我个人而言，我会将我的脚本保存为脚本包，然后我会制作一些php/Ruby/perl/python/任何脚本来解析包中的XML（因为我对它比较熟悉）。然后我将使用AppleScript，然后将XML从cURL传递给解析器脚本

AppleScript：

set scriptPath to POSIX path of (path to me as alias) & "Contents/Resources/parse_xml.rb"
set fooValue to do shell script "curl http://foo/test.xml 2> /dev/null | ruby " & quoted form of scriptPath

parse_xml.rb可能是这样的（以Ruby为例）：

需要“rexml/document”
#从stdin加载并解析xml
xml=STDIN.read
doc=REXML:：Document.new（xml）
#输出除去前导/尾随空格的根元素（）的文本
放置doc.root.text.strip

（Ruby和REXML包应该可以在任何Mac上随时使用，所以它应该可以在任何地方工作……我相信）

关键是，当脚本运行时，它将下载带有cURL的XML文件，并将其传递给Ruby脚本，最后，AppleScript中的

fooValue

将设置为“bar”

当然，如果XML更复杂，则需要编写更多脚本，或者再看看其他选项

可能有更多的方法可以做到这一点（例如，您可以只进行一些字符串操作，而不是完全进行XML解析，但这当然有点脆弱），但我就到此为止：）

以下是我所做的：

set file_tgt to (POSIX path of (path to temporary items)) & "file.xml"
    do shell script "curl -L " & "http://url.com/file.xml" & " -o " & file_tgt
tell application "System Events"
    set file_content to contents of XML file file_tgt
    tell file_content
        set my_value to value of XML element 1
    end tell
end tell

---

最初我使用“URL访问脚本”应用程序获取文件，但由于它在Lion中已被删除，我转而使用pure curl，它可以在Snow Leopard和Lion下工作。

意识到这是一个老问题，但这里有一种使用Bing Maps API的方法（注意，我用

xxxxxxxxx

替换了我的API密钥）。使用

do shell script

和

curl

来检索XML，然后沿着元素往下走，直到找到所需的元素（您可以将所有

tell

s合并到

tell XML元素“X”或XML元素“y”的
XML元素中……
，但这更容易理解）

编辑：我想我应该包括我在上面使用的XML：
