It simply extracts all the h2 nodes which have got ‘a’ tag present. The command looks a bit scary!! But don’t be. We can experiment to fetch other article headings by changing the value inside the box bracket. Similar to the above, all the h2 tags which are last in the tree structure will be extracted.

Our ‘position’ command extracts the first value because of in the command. As explained earlier, this will generate a character of 22 values. We are trying to locate all the h2 tags which have got the first position in the node tree structure. XpathSApply ( parsed_doc, '//h2', xmlValue ) Let us take a look if this XPath is correctly identified by Firefox. It starts with ‘/’ and traverses from the root node to the target node. The XPath provided above is called the absolute path. Absolute and Relative XPath Absolute Path – The XPath copied is /html/body/div/div/div/div/div/div/article/header/h2/a.

It will be used to resolve prefixes within the XPath itself, so that they can be matched with the document. namespaceResolver: The function that will be passed any namespace prefixes and should return a string representing the namespace URI associated with that prefix.

Common practice is to pass document as the context node.

contextNode: Specifies the context node for the query.

xpathExpression: The string representing the XPath to be evaluated.

The syntax is: var xpathResult = document.evaluate( To identify a WebElement using xpath and javascript you have to use the evaluate() method which evaluates an xpath expression and returns a result.ĭocument.evaluate() returns an XPathResult based on an XPath expression and other given parameters.
