Selecting meta tags with Selenium

Question

I want to extract data from a meta tag but the tag is as follows

<meta property="og:description" content="blah"/>

Since there is no id/class/etc. I can't use

driver.FindElement(By.[id/class/etc.]);

This meta tag has a unique property and content so I am wondering if there is any better way to locate and extract the content than selecting all "meta" tags and iterating through them.

Answer 1

您可以使用xPath来获取指定的meta标签

driver.FindElement(By.XPath("//meta[@property='og:description']"));

Answer 2

While extracting data from a meta tag, I would suggest to use the attributes as much as possible. In your case :

• XPath:

   driver.FindElement(By.XPath("//meta[@property='og:description' and @content='blah']")); 

• CssSelector:

   driver.FindElement(By.CssSelector("meta[property='og:description'][content='blah']")); 

Answer 3

You can use this xpaths

driver.FindElement(By.XPath("//meta[contains(@property,'og:description']"));

or

driver.FindElement(By.XPath("//meta[contains(@property,'og:description') and contains(@content,'blah')]"));
