问题描述
我通过 PHP 回声向 AJAX 调用发送一个 XML 文档来响应它.为了形成这个 XML 文档，我遍历了一个数据库的记录.问题是数据库包含具有<"的记录其中的符号.很自然地，浏览器会在该特定位置抛出错误.如何解决这个问题?
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
通过使用 htmlspecialchars，或者，也许更合适的是，使用库来构建 XML 文档，例如 DOMDocument 或XMLWriter.
另一种选择是使用 CDATA 部分，但是您必须注意 ]]> 的出现.
Another alternative would be to use CDATA sections, but then you'd have to look out for occurrences of ]]>.
还要考虑到您必须遵守为 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).
