Validation Failed: "EntityRef: expecting ';'"
提问by Laxmidi
Hi I've got some XML that won't validate. I've narrowed down the problem to this bit:
嗨，我有一些无法验证的 XML。我已经将问题缩小到这一点：
<script type="text/javascript">document.getelementbyid("oxm-1f4a4485-5a1d-45f9-a989-9c65a0b9ceb6").src="http://bid.website.net/display?l=h4siaaaaaaaaad2nmq6cqbrenycw7qjyolfccxmregvcoae0u0sly_agtvaewwn4bg_havwbnebpvmzkkzra_kzzdvoloq4u-hjnp7sii0rxcbzz5vl5kxsrds6wtsfbxmcr9chysuhqbecuckb8cvx4m-pbcxugtdrll6d3dqtihnqukth2yvdkptr67cuzfvlxjlinkul9634lpal_h4mwhso8aabzhw1cdcwjxl6xivgv8agrjxjc_gaaaa==&p=h4siaaaaaaaaabxkmq7cmaxaurcqjjrrsfqqsrm7x3fsrwyvosda8qnj_3ojfgb49o45pblq7e80syzjhopggso9wyzpcpntzkxk1ldtbbi7otmxfj9da1wpjcf10vtxdj9e5_utyj19k2lfssepld5agnqaaaa=&url=http%3a%2f%2flocalhost%2fproject-debug%2fproject.html";</script>
I put it in an XML validator and it spat out:
我把它放在一个 XML 验证器中，它吐出来了：
This page contains the following errors: error on line 1 at column 16: EntityRef: expecting ';'
此页面包含以下错误：第 1 行第 16 列错误：EntityRef：期望 ';'
Any ideas as to where the missing ';' is supposed to go? Is there another problem?
关于缺少“;”的任何想法 应该去？还有其他问题吗？

You have unescaped ampersands &in your URL. They either need to be (a) changed to character entities (&), or (b) enclosed in a CDATA section.
您&的 URL 中有未转义的 & 符号。它们要么需要 (a) 更改为字符实体 ( &)，要么 (b) 包含在 CDATA 部分中。
A CDATA section lets you leave special characters like &unescaped, so that'd be easiest:
CDATA 部分可让您保留特殊字符，&如未转义，这样最简单：
<script type="text/javascript">
// <![CDATA[
document.getElementById(...).src="...";
// ]]>
</script>
You can include anything you want inside of a CDATA section aside from the exact character sequence ]]>. The //comments are there to make sure browsers that don't understand CDATA sections ignore the <![CDATA[and ]]>markers.
除了确切的字符序列之外，您可以在 CDATA 部分中包含任何您想要的内容]]>。这些//注释是为了确保不理解 CDATA 部分的浏览器忽略<![CDATA[和]]>标记。
By the way, JavaScript is case sensitive. That should be getElementByIdnot getelementbyid.
顺便说一下，JavaScript 区分大小写。这应该是getElementById没有getelementbyid。

modifying the content isn't always possible, e.g if you're scraping a website.
修改内容并不总是可能的，例如，如果您正在抓取网站。
you can't just str_replace '&' with '&' because the html might include valid html entities, and you'd get something like "&amp;"
你不能只是 str_replace '&' 与 '&' 因为 html 可能包含有效的 html 实体，您会得到类似“&”的内容
Here's a regex which should replace ampersands with htmlentiries for ampersands, without breaking good htmlentities:
这是一个正则表达式，它应该用 htmlentiries 替换 & 符号，而不会破坏好的 htmlentities：
$html = preg_replace("|&([^;]+?)[\s<&]|","& ",$html);
I used it to scrape about 700 pages without any problems :)
我用它刮了大约 700 页没有任何问题:)
