我正在尝试访问XML文件层次结构中深层次的一些数据。
<ozml>
<scene>
<layer name=" Master Project Group" id="3097594133">
<layer name=" Focus Group" id="3097594131">
<layer name="⏹ Title Group" id="3097594129">
<layer name=" Main Title Group" id="3111213570">
<scenenode name="Main Title" id="3097595437" factoryID="61" version="5">
<parameter name="Object" id="2" flags="8589938704">
<parameter name="Text" id="369" flags="8606777344">
<text>DATA THAT I WANT</text>
</parameter>
</parameter>
</scenenode>
</layer>
</layer>
</layer
</layer
</scene>
</ozml>
这是我的代码，我试图通过层次结构访问数据。
tell application "System Events"
set theXMLFile to XML file myFile
set myData to (XML elements of XML element "parameter" of XML element "parameter" of XML element "scenenode" of XML element "layer" of XML element "layer" of XML element "layer" of XML element "layer" of XML element "scene" of XML element "ozml" of theXMLFile whose name is "text")
set textList to {}
repeat with i from 1 to (count myData)
set end of textList to value of item i of myData
end repeat
end tell
display dialog textList as string
我一直在收到错误，因为它无法找到特定的元素列表，但我确信这就是层次结构。我想知道是否存在多个具有相同名称的XML元素级别导致该问题。是否可以在两个文本括号之间获取数据？
答案 0 :(得分：1)
解决方案很简单：
1 2 3 4
2 4 some_value 6
4 5 6 7
3 4 5 6
您在上面标有①和②的行上有两个缺少右括号（ </scenenode>
</layer>
</layer>
</layer <!-- ① //-->
</layer <!-- ② //-->
</scene>
</ozml>
）。你的脚本可以正常工作。

我不知道这是否是最好的方法，但这就是我开始工作的方式。
set myUUIDListNew to {}
tell application "System Events"
tell XML file myXMLFile
tell XML element "scene" of XML element "ozml"
set theFactoryElements to (every XML element whose name = "layer")
repeat with a from 1 to length of theFactoryElements
set theCurrentFactoryElement to item a of theFactoryElements
tell theCurrentFactoryElement
set theUUID to value of XML attribute "name"
if theUUID = " Master Project Group" then
set secondLayer to (every XML element whose name is "layer")
repeat with a from 1 to length of secondLayer
set theCurrentLayerElement to item a of secondLayer
tell theCurrentLayerElement
set the2nd to value of XML attribute "name"
if the2nd = " Focus Group" then
set thirdLayer to (every XML element whose name is "layer")
repeat with a from 1 to length of thirdLayer
set theThirdLayerElement to item a of thirdLayer
tell theThirdLayerElement
set the3rd to value of XML attribute "name"
if the3rd = "⏹ Title Group" then
set fourthLayer to (every XML element whose name is "layer")
repeat with a from 1 to length of fourthLayer
set theFourthLayerElement to item a of fourthLayer
tell theFourthLayerElement
set the4th to value of XML attribute "name"
if the4th = " Main Title Group" then
set scenenodeLayer to (every XML element whose name is "scenenode")
repeat with a from 1 to length of scenenodeLayer
set thescenenodeElement to item a of scenenodeLayer
tell thescenenodeElement
set theSceneNode to value of XML attribute "name"
if theSceneNode = "Main Title" then
set parameterLayer to (every XML element whose name is "parameter")
repeat with a from 1 to length of parameterLayer
set theParameterElement to item a of parameterLayer
tell theParameterElement
set param1 to value of XML attribute "name"
if param1 = "Object" then
set parameter1Layer to (every XML element whose name is "parameter")
repeat with a from 1 to length of parameter1Layer
set theSecondParameterElement to item a of parameter1Layer
tell theSecondParameterElement
set param2 to value of XML attribute "name"
if param2 = "Text" then
set theBookName to value of XML element "text"
set end of myUUIDListNew to theBookName & return
