html5-parser is a Python library for parsing HTML and XML documents.

A fast implementation of the HTML 5 parsing spec for Python. Parsing is done in C using a variant of the gumbo parser. The gumbo parse tree is then transformed into an lxml tree, also in C, yielding parse times that can be a thirtieth of the html5lib parse times. That is a speedup of 30x. This differs, for instance, from the gumbo python bindings, where the initial parsing is done in C but the transformation into the final tree is done in python.

It is built on top of the popular lxml library and provides a simple and intuitive API for working with the document's structure.

html5-parser uses the HTML5 parsing algorithm, which is more lenient and forgiving than the traditional XML-based parsing algorithm. This means that it can parse HTML documents with malformed or missing tags and still produce a usable parse tree.

To use html5-parser, you first need to install it via pip by running pip install html5-parser. Once it is installed, you can use the html5_parser.parse() function to parse an HTML document and create a parse tree. For example:

``` from html5_parser import parse

html_string = "Hello, World!" root = parse(html_string) print(root.tag) # html ` You can also use `html5_parser.parse() with file-like objects, bytes or file paths.

Once you have a parse tree, you can use the find() and findall() methods to search for elements in the document similar to BeautifulSoup.

html5-parser also supports searching using xpath, similar to lxml.

htmlquery is a Go library that allows you to parse and extract data from HTML documents using XPath expressions. It provides a simple and intuitive API for traversing and querying the HTML tree structure, and it is built on top of the popular Goquery library.

Example Use


```python from html5_parser import parse html_string = "Hello, World!" root = parse(html_string) print(root.tag) # html body = root.find("body") # or find all print(body.text) # "Hello, World!" for el in root.findall("p"): print(el.text) # "Hello ```
```go package main import ( "fmt" "log" "github.com/antchfx/htmlquery" ) func main() { // Parse the HTML string doc, err := htmlquery.Parse([]byte(`

Hello, World!

  • Item 1
  • Item 2
  • Item 3
`)) if err != nil { log.Fatal(err) } // Extract the text of the first

element h1 := htmlquery.FindOne(doc, "//h1") fmt.Println(htmlquery.InnerText(h1)) // "Hello, World!" // Extract the text of all
  • elements lis := htmlquery.Find(doc, "//li") for _, li := range lis { fmt.Println(htmlquery.InnerText(li)) } // "Item 1" // "Item 2" // "Item 3" } ```
