Question

在Applescript中，有没有办法只根据tag属性获取标记块？例如，我只想抓取具有与之关联的属性“style”的标记块。（我包括一个缩短的xml。）

shortened xml file:
<?xml version="1.0" encoding="utf-8" standalone="no"?>
<templateDescription>
    <toolbars>
          <toolbarControls style="textToolbar">
          </toolbarControls>
          <toolbarControls style="textToolbar">
          </toolbarControls>
          <toolbarControls definition="image">
          </toolbarControls>
        </toolbars>
</templateDescription>


    set XMLFile to "Macintosh HD:Users:<user>:Desktop:templateDescription.xml"
        tell application "System Events"
            set toolbarControls to XML elements of XML element "toolbars" of XML element 1 of contents of XMLFile
            return every item of toolbarControls whose value of XML attribute "style" of XML element "toolbarControls" of XML element "toolbars" of XML element 1 of contents of XMLFile is "textToolbar"
        end tell

*新的复杂性：所以，我刚刚意识到有些xmls使用注释，并且系统事件存在一个已知错误，当有注释时它无法正确解析xml。有没有办法解决这个问题？

使用循环来抓取标记块。

像这样：

set XMLFile to "Macintosh HD:Users:<user>:Desktop:templateDescription.xml"
set toolbarControls_textToolbar to {}
tell application "System Events"
    set toolbarControls to XML elements of XML element "toolbars" of XML element 1 of contents of XML file XMLFile
    repeat with xmlElem in toolbarControls
        try
            tell xmlElem to if value of XML attribute "style" is "textToolbar" then set end of toolbarControls_textToolbar to contents
        end try
    end repeat
end tell
return toolbarControls_textToolbar -- return every XML element whose value of XML attribute "style" is "textToolbar"

使用Applescript解析XML并基于xml属性引用标记块
