使用XPath的SelectNodes忽略个案(SelectNodes with XPath ignoring cases)

使用XPath的SelectNodes忽略个案(SelectNodes with XPath ignoring cases)

在XPath中找到包含特定字符串而忽略字符外框的元素时遇到问题。

我想在HTML页面中找到所有带有id的节点都包含文本“footer”，忽略它以大写或小写写入。

在我的例子中，我有一个不同的html文本，如下所示：

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

我需要使用XPath选择所有节点（或任何组合中的“footer”）。

目前我正在使用此xpath，但不适用于UpperCase ID

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

我用translate（）做了几个测试，但是没有按我的预期工作。

任何想法？

编辑：我使用HtmlAgilityPack与XPath 1.0版本的作品。

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

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.

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>

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

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

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

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

Any idea?

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

不知道你是否已经尝试过这种方式，但这是我为区分大小写而包含搜索的做法：

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

我看到你找到了你的解决方案，所以我发布了这个答案，以防其他人有同样的问题。

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

I saw you have found your solution, so I'm posting this answer in case others have the same issue.
