This article introduces Spiderman, a Java-based open‑source web scraping tool that uses XPath and regular expressions, explains its micro‑kernel plugin architecture, and provides step‑by‑step instructions for configuring and running the tool to extract data from target web pages.
Spiderman is an open‑source Java tool designed for web data extraction, allowing users to collect specified web pages and extract useful information.
The tool leverages basic technologies such as XPath and regular expressions, and its micro‑kernel with plugin architecture offers strong extensibility, flexible secondary development, and multithreaded performance without requiring users to write code.
Three Simple Steps to Use Spiderman
Identify the target website and the specific page you want to scrape.
Open the target page and obtain the page's XPath.
Fill in the parameters in the XML configuration file and run Spiderman.
How to Obtain XPath for a Page Element
Download the xpathonclick plugin (provided in the project) and install it in Chrome.
After installation, click the new icon in the Chrome toolbar, then click the element on the page whose XPath you need.
Press F12 to open the JavaScript console, scroll to the bottom to see the generated XPath string, and modify it as necessary using XPath syntax.
