要求：將下圖xml信息轉化成json對象
轉化後的結果爲：
<script type="text/javascript">
var myObject = {
"section":{
"title":"Book-Signing Event",
"signing":[ //用數組表示
{
"author":{"title":"Mr","name":"Vikram Seth"},
"book" :{"title":"A Suitable Day","price":"$22.95"}
},
{
"author":{"title":"Dr","name":"Oliver Sacks"},
"book" :{"title":"The Island of Color","price":"$12.98"}
}
]
}
};
alert(myObject.section.title); //Book-Signing Event
alert(myObject.section.signing[0].book.title); //A Suitable Day
</script>
