What is HTML Entity ' '?
提问by ford
I'm generating an XML Document object via the DOMDocument class. In the process, some kind of whitespace within elements is being converted into . It's pretty difficult to search for this one since search engines treat this character as whitespace.
我正在通过 DOMDocument 类生成一个 XML Document 对象。在此过程中，元素中的某种空白被转换为 . 搜索此字符非常困难，因为搜索引擎将此字符视为空格。
How do I scrub this character out of my xml output, or at least replace it with a different, preferable whitespace character?
我如何从我的 xml 输出中清除这个字符，或者至少用一个不同的、更可取的空白字符替换它？
Thanks.
谢谢。

ASCII code 13 corresponds to a carriage return (in PHP, it's "\r").
ASCII 码 13 对应于回车（在 PHP 中，它是"\r"）。

You scrub this character out of your output by not putting it there in the first place. Look for the code that puts the carriage return in your XML, and delete it.
您可以通过不首先将其放在输出中来将该字符从输出中删除。查找将回车符放入 XML 的代码，然后将其删除。
