XML 属性值中是否允许换行? [英] Are line breaks in XML attribute values allowed?

问题描述

我意识到它并不优雅或不受欢迎，但它是否允许(在格式良好的 XML 中)XML 元素中的属性值跨越多行?

I realise that it's not elegant or desired, but is it allowed (in well-formed XML) for an attribute value in an XML element to span multiple lines?

例如

<some-xml-element value="this value goes over....
multiple lines!" />

是的，我意识到有更好的写法.我个人会这样写:

Yeah I realise there's better ways of writing that. I would personally write it like:

<some-xml-element>
<value>this value goes over...
multiple lines!</value>
</some-xml-element>

或:

<some-xml-element value="this value goes over....&#13;&#10;" />

但是我们有自己的 XML 解析器，我想知道第一个示例是否允许在格式良好的 XML 中.

But we have our own XML parser and I'd like to know whether the first example is allowed in well-formed XML.

似乎除了 <、& 和你的分隔符(' 或 ")之外的所有内容没关系.所以换行符也应该是.

Seems to say everything except <, &, and your delimiter (' or ") are OK. So newline should be, too.
