无法使用xsl获取xml标记的值 - （xsl：value-of）

Question

XML代码：

func play( data: NSData ) {
var audioFile: AVAudioFile
var audioBuffer: AVAudioPCMBuffer
// writing the data
let destPath = NSTemporaryDirectory() + "chunk.mp3"
data.writeToFile( destPath, atomically: true )
// initializing the AVAudioFile
audioFile = AVAudioFile( forReading: NSURL(string: destPath)!)
// initializing the AVAudioPCMBuffer
audioBuffer = AVAudioPCMBuffer(PCMFormat: audioFile.processingFormat,
                               frameCapacity: UInt32(data.length))
audioFile.readIntoBuffer( audioBuffer )
/*
    I didn't put any AVAudioPlayerNode/AVAudioEngine in this code to keep it simple and describe the situation,
    anyway this works fine when everything's properly initialized:
*/
player.scheduleBuffer( audioBuffer, completionHandler: nil )
}

XSL代码：

  <complextype name="submission">
    <sequence>
      <file-audit-data></file-audit-data>
      <submission-period-from-date>01/01/2014</submission-period-from-date>
      <submission-period-to-date>12/31/2014</submission-period-to-date>
      <aco-gpro></aco-gpro>
    </sequence>
    <attributeGroup ref="submissionAttributeGroup" />
  </complextype>

它根本不会进入每个人，请帮助我理解造成问题的原因......

你xsl：foreach在＆＃39; complextype＆＃39;节点，不在＆＃39;序列＆＃39;节点。试试这个：＆＃34;＆lt; xsl：for-each select =＆＃34; // complextype [@name =＆＃39;提交＆＃39;] /序列＆＃34;＆gt;＆＃34;
