問題描述
我有 Google 結帳沙箱生成的 HTML 代碼，可以在 HTML 頁面中正常工作.當我將相同的代碼放在 XHTML 頁面中時，它會引發以下異常:
I have Google checkout sandbox generated HTML code which works fine in HTML page. When I put the same code in XHTML page, it throws the below exception:
對實體w"的引用必須以;"結尾分隔符
the reference to entity "w" must end with the ';' delimiter
它在下面的src屬性中引用了URL中的請求參數w:
It's referring the request parameter w in the URL in the below src attribute:
<input type="image" name="Google Checkout" alt="Fast checkout through Google"
src="http://sandbox.google.com/checkout/buttons/checkout.gif?merchant_id=211512493599623&w=180&h=46&style=white&variant=text&loc=en_US"
height="46" width="180" />
這是怎么引起的，我該如何解決?
How is this caused and how can I solve it?
推薦答案
與號 & 是 HTML 和 XML 中的特殊字符.如果要將其用作普通字符，則必須對其進行正確編碼.用 & 代替 &:
The ampersand & is a special character in HTML and XML. If you want to use it as a normal character, you have to encode it correctly. Write & instead of &:
src="...9623&w=180&h=46&style=white&variant=text&loc=en_US"
& 表示編碼實體的開始，例如 < 表示 <，或 & 用于 &.在您的情況下，解析器嘗試將 &w 解釋為實體.但是實體總是由 ; 終止，因此如果 ; 丟失，您會收到錯誤消息.
& denotes the start of an encoded entity, such as < for <, or & for &. In your case the parser tries to interpret &w as an entity. But entities are always terminated by an ;, thus if the ; is missing you get the error message.
