What is the Clojure Equivalent of Python's lxml Library?

Question

What is the Clojure equivalent to Python's lxml library?

Answer

Clojure does not have a direct equivalent to Python's lxml, but there are several libraries that offer XML parsing and manipulation capabilities suitable for most requirements.

;; Basic XML parsing using `clojure.xml`
(require '[clojure.xml :as xml])

(defn parse-xml [input]
  (with-open [rdr (clojure.java.io/reader input)]
    (xml/parse rdr))) 

;; Example of using Enlive for querying
(require '[net.cgrand.enlive-html :as enlive])

(enlive/select (enlive/html-resource "file.xml") [:your-tag])

Causes

  • Lack of a single definitive library like lxml in Clojure
  • Different approaches to XML processing in functional programming compared to Python

Solutions

  • Use the `clojure.xml` library for basic XML parsing and manipulation.
  • Explore `enlive` for more sophisticated XML/HTML querying and transformation.
  • Consider `hiccup` for creating HTML or XML structures in a more Clojure-like way.

Common Mistakes

Mistake: Attempting to use a library that is not designed for XML parsing

Solution: Review the library documentation to ensure it supports your XML handling requirements.

Mistake: Not utilizing Clojure's lazy sequences for large XML documents

Solution: Leverage lazy sequences to manage memory efficiently while processing large XML files.

Helpers

  • Clojure XML libraries
  • Clojure equivalent of lxml
  • XML parsing in Clojure
  • enlive Clojure library
  • clojure.xml usage
