This is a simple HTML parser for Node.js, created using htmlparser2 package. It provides a HtmlParser class which can be used to query and manipulate HTML documents. The class also provides some useful methods like getAttribute, getText, getParent, getChildren, getOuterHTML, getInnerHTML, getNext, getPrev, querySelector, querySelectorAll, and getListData.
You can install this package using npm:
npm install @hd/html-parser
Here's an example of how to use this package:
import HDHtmlParser from '@hd/html-parser';const html =
<html> <head> <title>My title</title> </head> <body> <h1>Heading 1</h1> <p>Paragraph 1</p> <p>Paragraph 2</p> </body> </html>;
const document = await HDHtmlParser(html); const title = document .querySelector('title') .getText(); const paragraphs = document .querySelectorAll('p') .map(p => p.getText());
The HtmlParser class provides the following
methods:
querySelector(selector: string): HtmlParser | nullReturns a new
HtmlParser object that matches the first element in the document that matches the specified selector
, or null if no such element exists.
querySelectorAll(selector: string):
HtmlParser[]Returns an array of HtmlParser objects that match all elements in the document
that match the specified selector. If no elements match, an empty array is returned.
getHtml(): string | nullReturns the HTML string of the document, or null if an error
occurs.
getAttribute(name: string): string | null | undefinedReturns the value of the
specified attribute on the current element, or null if the attribute does not exist or an error
occurs.
getText(): string | nullReturns the text content of the current element, or
null if an error occurs.
getParent(): HtmlParserReturns a new HtmlParser
object that represents the parent of the current element.
getChildren(): HtmlParser[]Returns
an array of HtmlParser objects that represent the children of the current element.
getOuterHTML(): string | nullReturns the outer HTML of the current element, or null if an
error occurs.
getInnerHTML(): string | nullReturns the inner HTML of the current element, or an empty string if the element has no children.
getNext(): HtmlParser | nullReturns a
new HtmlParser object that represents the next sibling of the current element, or null if no
such element exists.
getPrev(): HtmlParser | nullReturns a new HtmlParser
object that represents the previous sibling of the current element, or null if no such element
exists.
getListData(selector: string, itemsSelector: any, meta: any): object | nullReturns
an object that represents the data extracted from a list of elements that match the specified selector.
The itemsSelector argument is an object that maps the keys of the output object to functions that extract
the data from the corresponding elements. The meta argument is an object that can be used to pass
additional information to the extractor functions. Returns null if an error occurs.
This is the main function of the package. It takes an HTML string
