This part of the expression is called the axis and it specifies a set of nodes to select from, based on their direction on the tree from the current context (downwards, upwards, on the same tree level). So, // in the abbreviated syntax is short for descendant-or-self, which means the current node or any node below it in the tree.

Translating //title to the full syntax we get: /descendant-or-self::node()/child::title In fact, the expressions we've just seen are using XPath's abbreviated syntax. In this example, // is the axis and title is the node test. This means: look in the whole tree, starting from the root of the tree ( //) and select only those nodes whose name matches title.

However, we usually don't know or don’t care about the full explicit node-by-node path, we just care about the nodes with a given name. For example, the head node is the context node when the last step is being evaluated. It roughly means: start from the ‘html’ element, look for a ‘head’ element underneath, and a ‘title’ element underneath that ‘head’. The location path above has three location steps, separated by slashes. It allows us to specify the path from the context node (in this case the root of the tree) to the element we want to select, as we do when addressing files in a file system. Here is how we can select the title element from the page above using an XPath expression: /html/head/title Text node: represents the text enclosed in an element node ( example in example).ĭistinguishing between these different types is useful to understand how XPath expressions work.Comment node: represents comments in the document ( ).Attribute node: represents an attribute from an element node, e.g.Element node: represents an HTML element, a.k.a an HTML tag.This is how the XPath tree for the HTML document looks like:Īs you can see, there are many node types in an XPath tree: It is in fact the parent of the document element node ( in case of the HTML above). This tree's root node is not part of the document itself. XPath handles any XML/HTML document as a tree. Just paste the HTML samples provided in this post and play with the expressions. Note: You can use the XPath playground to experiment with XPath. This is an introductory XPath tutorial will walk you through the basic concepts of XPath, crucial to a good understanding of it, before diving into more complex use cases. So when you are scraping the web and you run into a hard-to-scrape website, XPath may just save the day (and a bunch of your time!). With XPath, you can extract data based on text elements' contents, and not only on the page structure. The other is CSS and while CSS selectors are a popular choice, XPath can actually allow you to do more. It allows you to select nodes or compute values from an XML or HTML document and is actually one of the languages that you can use to extract web data using Scrapy. Once it is visible then you can perform your operations.Let's start with what is XPath? XPath is a powerful language that is often used for scraping the web. Use Explicit waitfeature of Selenium and wait till the element is not visible. If you are trying to access some particular element on Webpage that is not currently visible, in this case also you will get the Element, not visible exception.ĮlementNotVisible Exception in Selenium Solutions for ElementNotVisibleException in Selenium Webdriverįirst Solution: Try to write unique XPATH that matches with a single element only.
