的NSXMLParser訪問字符串值誤差

Question

我有這樣

<?xml version="1.0" encoding="UTF-8"?> 
<java version="1.6.0_27" class="java.beans.XMLDecoder"> 
<object class="java.util.ArrayList"> 
    <void method="add"> 
    <object class="impl.DictSpotIndexImpl"> 
    <void property="englishMeaning"> 
    <string></string> 
    </void> 
    <void property="englishWordName"> 
    <string> dendritical</string> 
    </void> 
    <void property="tamilMeaning"> 
    <string>Empty</string> 
    </void> 
    <void property="tamilWordName"> 
    <string>மரம் போன்ற வரைததடங்களையுடைய படி அடுக்கியற் பாறை</string> 
    </void> 
    <void property="wordClass"> 
    <string>regular</string> 
    </void> 
    <void property="wordConstraints"> 
    <string></string> 
    </void> 
    <void property="wordDataSource"> 
    <string>Source Not found</string> 
    </void> 
    <void property="wordImages"> 
    <string></string> 
    </void> 
    <void property="wordPopularity"> 
    <string></string> 
    </void> 
    <void property="wordTypes"> 
    <string>பெயரடை</string> 
    </void> 
    </object> 
    </void> 
</object> 
</java> 

XML數據現在，我想這是屬性tamilWordName內的值。我怎樣才能做到這一點。？ 任何建議將非常感激。

到目前爲止，我試過這樣，真的不知道如何處理屬性。

     if elementName == "void.tamilWordName" 
     { 
      println(elementName) 
     } 


    } 

    func parser(parser: NSXMLParser, foundCharacters string: String) 
    { 

    } 


    func parser(parser: NSXMLParser, didEndElement elementName: String, namespaceURI: String, qualifiedName qName: String) 
    { 


    } 



    func parser(parser: NSXMLParser, parseErrorOccurred parseError: NSError) 
    { 

    } 





}

這是處理屬性的代碼片段。

如果元素名稱爲void，則必須檢查屬性。 如果存在名稱爲property的屬性，請檢查值是否爲tamilWordName。一旦你發現所有的層次，設置一個布爾標誌並等待下一個元素進入didStartElement。只要您在didEndElement中找到元素名稱void，就可以對其進行處理。

func parser(parser: NSXMLParser!, didStartElement elementName: String!, namespaceURI: String!, qualifiedName qName: String!, attributes attributeDict: [NSObject : AnyObject]!) { 
    self.currentElement = elementName // helper variable to hold the current element 

    if elementName == "void" { 
     let attrs = attributeDict as [String: NSString] 

     if let prop = attrs["property"] { 
      if prop == "tamilWordName" { 
       // found it, now set a boolean property variable and process the elements coming 
       self.tamilWordName = true 
      } 
     } 
    } 
} 

func parser(parser: NSXMLParser!, foundCharacters string: String!) { 
    if currentElement == "string" && self.tamilWordName { 
     // append to variable which holds the string 
     self.tamilWordString += string 
    }   
} 

func parser(parser: NSXMLParser!, didEndElement elementName: String!, namespaceURI: String!, qualifiedName qName: String!) { 
    if elementName == "string" && self.tamilWordName { 
     // string element inside tamilWordName closed, process it here 
    } 
    else if elementName == "void" && self.tamilWordName { 
     // void element with property tamilWordName closed 
     self.tamilWordName = false 
    }    
} 

我希望你在這裏得到的想法。
