如何使字符串XML“安全”？ [英] How do you make strings XML"safe"?

问题描述

我回复一个AJAX调用通过PHP echos发送一个XML文档。为了形成这个XML文档，我循环遍历数据库的记录。问题是数据库包括在其中具有<符号的记录。因此，浏览器自然会在该特定位置抛出错误。

I am responding to an AJAX call by sending it an XML document through PHP echos. In order to form this XML document, I loop through the records of a database. The problem is that the database includes records that have '<' symbols in them. So naturally, the browser throws an error at that particular spot. How can this be fixed?

推荐答案

通过转义 htmlspecialchars ，或者更合适的是使用库来构建XML文档，例如 DOMDocument 或 XMLWriter 。

另一个另一种方法是使用CDATA节，但是您必须注意出现]]> 。

Another alternative would be to use CDATA sections, but then you'd have to look out for occurrences of ]]>.

还要考虑到您必须尊重为XML文档定义的编码（默认为UTF-8）。

Take also into consideration that that you must respect the encoding you define for the XML document (by default UTF-8).
