如何在XML中搜索給定的字符串？

Question

我有一個像XML：

<bodyText> 
    <1 beginIndex="0" endIndex="723"> 
    The teddy bear is a soft toy in the form of a bear. Teddy bears are among the most popular gifts for children and are often given to adults to signify love, congratulations or sympathy.</1> 

<2 beginIndex="724" endIndex="347"> 
    Morris Michtom saw the drawing of Roosevelt and was inspired to create a new toy. He created a little stuffed bear cub and put it in his shop window with a sign that read "Teddy's bear," after sending a bear to Roosevelt and receiving permission to use his name. 
</2> 
</bodyText> 

我如何在XML搜索特定的字符串？ 例如：如果用戶輸入「羅斯福圖紙」。第二個xml元素包含這個字符串，它應該返回2（它應該返回段落號）。 如何找出？

Answer 1

將xml轉換爲一個內部類，讓我們調用它具有id的MyEntry（在你的例子中的1和2的值，但把它們作爲屬性，節點的名稱是不相關的，把「a」），beginIndex， endIndex的和值（你的字符串），並把裏面的MyEntry的方法中它像：

public function search(string:String):Boolean 
{ 
    return value.indexOf(string) != -1; 
} 

//When you search for the string "drawing of Roosevelt": 
for each(var entry:MyEntry in entries) 
{ 
    if(entry.search(string)) 
    { 
     trace("Found!"); 
     break; 
    } 
}
