php简单的xpath问题 [英] php simple xpath question

问题描述

我有这个 div:

Product1

我也有这个 div:

Product2

如何更改此 xpath 查询以获取包含产品名称的任何 div?而不是获得完全匹配.

/html/body//div[@class='product-name']

我用谷歌搜索了它，但我能找到的只是在搜索节点内的值而不是属性时如何使用 contains.

编辑

解决方案

您可以使用 contains():

/html/body//div[contains(@class, 'product-name')]

更新:

正如 @Alejandro 在他的评论中指出的那样，这也将匹配包含 产品名称.查看他对 XPath 1.0 解决方案的回答.

如果您使用 XPath 2.0，您也可以这样做:

/html/body//div[exists(index-of(tokenize(@class, "\s+"), "product-name"))]

I have this div:

<div class="product-name">Product1</div>

I also have this div:

<div class="product-name gold">Product2</div>

How can I alter this xpath query to get whatever divs which contains product-name? Instead of getting an exact match.

/html/body//div[@class='product-name']

I googled it, but all I could find is how to use contains when searching for a value within a node, and not an attribute.

EDIT

解决方案

You can use contains():

/html/body//div[contains(@class, 'product-name')]

Update:

As @Alejandro points out in his comment, this would also match any class that contains product-name. See his answer for a XPath 1.0 solution.

If you use XPath 2.0, you could also do this:

/html/body//div[exists(index-of(tokenize(@class, "\s+"), "product-name"))]
