我在查找包含某些字符串而忽略字符大小写的XPath中的元素时遇到问题。

I have a problem finding elements in XPath that's contains a certain string ignoring character casing.

我想在HTML页面中查找所有ID为id的节点文本页脚忽略大小写。

I want to find in a HTML page all the nodes with id contains the text "footer" ignoring it's write in uppercase or lowercase.

在我的示例中，我有一个不同的html文本，如下：

In my example I have a different html text like this:

<div id="footer">some text</div> <div id="anotherfooter">some text</div> <div id="AnotherFooter">some text</div> <div id="AnotherFooterAgain">some text</div>

我需要选择所有节点（或者在任何情况下都选择 footer一词的组合

I need to select all nodes (or any combination in any case with the word "footer" in the id) with a XPath.

当前我正在使用此xpath，但不适用于UpperCase id

Currently I'm using this xpath but doesn't work for the UpperCase id's

"//*[contains(./@id, 'footer')]/@id"

我已经完成了translate（）的多个测试，但是没有按预期工作。

I've done several tests with translate() but doesn't work as I expected.

有什么想法吗？

编辑：我正在将HtmlAgilityPack与XPath 1.0版本配合使用。

I'm using HtmlAgilityPack with works with the XPath 1.0 version.

推荐答案

不确定您是否尝试过此操作，但这是我针对区分大小写的内容所做的搜索：

Not sure if you've tried this yet, but this is what I do for case sensitive contains searches:

//*[contains(translate(./@id,'ABCDEFGHIJKLMNOPQRSTUVWXYZ','abcdefghijklmnopqrstuvwxyz'), 'footer')]/@id

我看到您已经找到了解决方案，所以我会发布此答案，以防其他人遇到相同的问题。
