FAQS About the CLJ Tagsoup Framework
CLJ TAGSOUP framework Frequently Asked Questions Questions Answers
ClJ Tagsoup is a CLOJURE library for parsing and processing HTML/XML documents.It provides a set of simple and easy -to -use functions and tools to enable developers to easily operate and extract data in HTML/XML.In this article, we will answer some common questions about the CLJ Tagsoup framework and provide some Java code examples.
Question 1: What is the CLJ Tagsoup framework?
The CLJ Tagsoup framework is a library used in the Clojure language to analyze and process HTML/XML documents.It is based on Java's Tagsoup library, provides Clojure -friendly API, and adds some additional functions and extensions.
Question 2: How do I use CLJ Tagsoup to resolve HTML documents?
First, you need to introduce the CLJ Tagsoup library in the dependence of the project.Then, you can use the following code example to resolve the HTML document:
import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
public class HtmlParserExample {
public static void main(String[] args) {
String html = "<html><body><h1>Hello, TagSoup!</h1></body></html>";
Document doc = Jsoup.parse(html);
System.out.println(doc.select("h1").text());
}
}
Question 3: What functions do CLJ TAGSOUP support?
ClJ Tagsoup provides a series of functions and tools that enable you to analyze, query and operate HTML/XML documents.It supports label selectors, attribute selectors, CSS selectors, etc., so that you can easily extract the data in the document.In addition, it also supports the processing of transit characters and neatization HTML documents.
Question 4: How to use CLJ Tagsoup for label selectioner query?
You can use the `Clojure.tagsoup.Select/Select` function to perform the label selectioner query.The following is an example:
(ns tagsoup.example
(:require [clojure.tagsoup.select :refer :all]))
(def html "<html><body><h1>Hello, TagSoup!</h1></body></html>")
(def doc (clojure.tagsoup.parse/parse-string html))
(def h1-text (select (node= :h1) doc))
(println (text h1-text))
Question 5: Does ClJ Tagsoup support XPATH query?
Unfortunately, CLJ Tagsoup does not directly support XPath query.However, you can use Clojure's `Data.xml` Library to convert the HTML/XML document to XML format, and then use XPath for query.
Question 6: How to handle the rush character?
Clj tagsoup will automatically handle the rigid character and convert it to the corresponding original character.For example, `& lt;` will be converted to `<`, `& gt;` will be converted to `>`, and so on.
Question 7: How does ClJ Tagsoup neatly clean HTML document?
You can use the `Clojure.tagsoup.clean/Clean` function to neatly clean the HTML document.This will delete incorrect or invalid labels in the document and correctly nested and closed the label.
(ns tagsoup.example
(:require [clojure.tagsoup.clean :refer [clean]]))
(def html "<div><p>Example</div></p>")
(def cleaned-html (clean html))
(println cleaned-html)
I hope that these common questions can help you better understand and use the CLJ Tagsoup framework.
