对XML里的属性或元素进行模糊搜索的方法

最近发现几个贴子都是问关于对XML的属性或元素进行模糊搜索的方法，在此发出代码片段示例，希望能够对你有所帮助；）
示例XML

private var xml:XML=
<employees>
        <employee>
            <name>Christina Coenraets</name>
            <phone>555-219-2270</phone>
            <email>[e-mail]</email>
            <active>true</active>
        </employee>
        <employee>
            <name>Joanne Wall</name>
            <phone>555-219-2012</phone>
            <email>[e-mail]</email>
            <active>true</active>
        </employee>
        <employee>
            <name>Maurice Smith</name>
            <phone>555-219-2012</phone>
            <email>[e-mail]</email>
            <active>false</active>
        </employee>
        <employee>
            <name>Mary Jones</name>
            <phone>555-219-2000</phone>
            <email>[e-mail]</email>
            <active>true</active>
        </employee>
        <employee>
            <name>Jack Jones</name>
            <phone>555-219-2000</phone>
            <email>[e-mail]</email>
            <active>true</active>
        </employee>
    </employees>

1.String检索法(区分大小写)

private function searchXML(index:String):XMLList{
        return xml.employee.(name.indexOf(index)>-1)
          }

private function searchXML(index:String):XMLList{
        return xml.employee.(name.search(new RegExp(index,"gi"))>-1)
          }1.正测检索法(不区分大小写)
