Compare parsel vs. regon

Parsel is a Python library licensed under BSD that facilitates the extraction and removal of data from HTML and XML documents using XPath and CSS selectors, with the option to integrate regular expressions. To begin, you create a selector object for the HTML or XML content you wish to analyze. After that, you can utilize either CSS or XPath expressions to target specific elements. CSS serves as a styling language for HTML, defining selectors that link styles to designated HTML elements, while XPath is utilized for selecting nodes within XML documents and can also be applied to HTML. Although both CSS and XPath can be used, CSS tends to offer greater readability, whereas XPath provides capabilities that may not be achievable through CSS alone. Built on top of lxml, parsel selectors incorporate some EXSLT extensions and come with pre-registered namespaces available for use in XPath queries. Furthermore, parsel selectors allow for the chaining of selectors, enabling users to primarily select by class using CSS and seamlessly transition to XPath when the situation demands it, enhancing flexibility in data extraction tasks. This dual capability makes parsel a powerful tool for developers working with web data.

litex.regon serves as a user-friendly interface for the Polish REGON database by providing a straightforward, Python-based wrapper. To utilize its SOAP API, users must obtain a user key from the administrators of REGON. The REGONAPI requires just one argument, which is the service URL provided by these administrators. Once logged in, users can initiate queries against the database. Queries can be made using a single REGON number (which can be either 9 or 14 digits), a single 10-digit KRS number, or a single NIP (which consists of a 10-digit string). Furthermore, users can query collections of REGONs, KRSs, or NIPs, ensuring that all items in a collection conform to the respective length requirements. The method only processes one parameter at a time, prioritizing the first one provided from the list. Additionally, users can request a more comprehensive report by including the detailed=True parameter, which prompts the search method to return a default detailed report. If a user is familiar with the REGON of a specific business entity and the name of the detailed report, they can retrieve the complete report directly, enhancing the accessibility of information within the database. This feature makes litex.regon a valuable tool for anyone needing detailed insights into Polish business entities.
