querySelector，通配符元素匹配？ [英] querySelector, wildcard element match?

问题描述

有没有办法使用 querySelector 或 querySelectorAll 进行通配符元素名称匹配？我在属性查询中看到对通配符的支持，但不支持元素本身。

我要解析的XML文档基本上是一个平面的属性列表，我需要找到在他们的名字中有某些字符串的元素。

我意识到如果我需要这个XML文档可能需要重组，但这不会发生。 / p>

任何解决方案，除了回到使用显然不推荐使用的XPath（IE9删除它）是可以接受的。

解决方案

[id ^ ='someId'] 将匹配从 someId 开始的所有ids。

[id $ ='someId'] 将匹配以 someId 。

[id * ='someId'] 将匹配所有包含 someId 。

如果您要查找名称属性只需用 name 替换 id 。

如果你在谈论元素的标签名称，我不相信有一种方法使用 querySelector

Is there a way to do a wildcard element name match using querySelector or querySelectorAll? I see support for wildcards in attribute queries but not for the elements themselves.

The XML document I'm trying to parse is basically a flat list of properties and I need to find elements that have certain strings in their names.

I realize the XML document is probably in need of a restructuring if I need this but that's just not going to happen.

Any solution except going back to using the apparently deprecated XPath (IE9 dropped it) is acceptable.

解决方案

[id^='someId'] will match all ids starting with someId.

[id$='someId'] will match all ids ending with someId.

[id*='someId'] will match all ids containing someId.

If you're looking for the name attribute just substitute id with name.

If you're talking about the tag name of the element I don't believe there is a way using querySelector
