selenium xpath中“//div [.// [text（）='Selenium']]”和“// div [// a [text（）='SELENIUM']]”之间的区别是什么？

Question

what is the difference between "//div[.//a[text()='SELENIUM']]" and "//div[//a[text()='SELENIUM']]" in selenium xpath.

Can some one please clarify my query on xpath, what is the difference when i give dot(.) before //a and without dot(.) .//a

you can use the above mentioned xpath's in this url " http://demo.guru99.com/selenium/guru99home/ " to see the difference.

Answer 1

//x searches the whole tree

.//x searches the subtree under the context node

So in a predicate, //div[//x] selects a div if there is an x anywhere in the document, while //div[.//x] selects a div if there is an x within the subtree rooted at that div .
