![]() The latter works because, if a node-set is passed into functions like string, XPath 1.0 just looks at the first node (in document order) in that node-set, and ignores the rest. To see the multiple text nodes, you can use: //example//text()Īnd to more clearly see the entire text content of an element, one can use the string function: string(//example) refers to the entire text content of the element and it's children. For simple text parsing regular expression can be used, but HTML is designed to be a machine-readable text structure so we can take advantage of this fact and use special path languages like css selectors and xpath. If you want to find text that spans multiple children/text nodes, then you can use. When it comes to parsing web scraped HTML content, there are multiple techniques to select data we want.

The following expression will return the element: //example 1) starts-with (string1, string2) When the first string begins with the second string, it returns true. To find an element containing specific text, you can use the contains function. Here we can see that the text() node specifier is optional when using normalize-space. Which will trim the surrounding whitespace before doing the comparison. That said, it might take a little while to get. ![]() This is because the element contains whitespace surrounding the hello text. Will return the hello element, but not the element.
