@xml-tools/parser
Advanced tools
@xml-tools/parser is an npm package that provides tools for parsing XML documents. It allows developers to convert XML strings into a structured format that can be easily manipulated and analyzed in JavaScript. The package is particularly useful for applications that need to process or transform XML data.
Parsing XML Strings
This feature allows you to parse an XML string into a structured JavaScript object. The `parse` function takes an XML string as input and returns a parsed representation of the XML document.
const { parse } = require('@xml-tools/parser');
const xmlText = '<note><to>Tove</to><from>Jani</from><heading>Reminder</heading><body>Don't forget me this weekend!</body></note>';
const parsedXML = parse(xmlText);
console.log(parsedXML);Handling Parsing Errors
This feature demonstrates how to handle errors that may occur during the parsing process. The `parse` function will throw an error if the XML string is not well-formed, which can be caught and handled appropriately.
const { parse } = require('@xml-tools/parser');
const xmlText = '<note><to>Tove</to><from>Jani</from><heading>Reminder</heading><body>Don't forget me this weekend!</body></note'; // Note the missing closing '>'
try {
const parsedXML = parse(xmlText);
console.log(parsedXML);
} catch (error) {
console.error('Parsing error:', error.message);
}xml2js is a popular npm package for converting XML to JavaScript objects. It provides a simple and flexible API for parsing XML strings and is widely used in the Node.js community. Compared to @xml-tools/parser, xml2js offers more customization options for the parsing process, such as explicit array handling and attribute grouping.
fast-xml-parser is another npm package designed for fast and efficient XML parsing. It is known for its performance and low memory footprint, making it suitable for high-performance applications. Unlike @xml-tools/parser, fast-xml-parser focuses on speed and efficiency, providing a lightweight alternative for XML parsing needs.
xmldom is an npm package that provides a DOM-like interface for XML parsing and serialization. It allows developers to work with XML documents using familiar DOM methods and properties. Compared to @xml-tools/parser, xmldom offers a more traditional approach to XML manipulation, similar to how XML is handled in web browsers.
A Fault Tolerant XML Parser which produces a Concrete Syntax Tree.
This means that the Parser will not stop on the first error and instead attempt to perform automatic error recovery. This also means that the CST outputted by the Parser may only have partial results. For example, In a valid XML an attribute must always have a value, however in the CST produced by this parser an attribute's value may be missing as the XML Text input is not necessarily valid.
The CST produced by this parser is often used as the input for other packages in the xml-tools scope, e.g:
With npm:
npm install @xml-tools/parserWith Yarn
yarn add @xml-tools/parserPlease see the TypeScript Definitions for full API details.
A simple usage example:
const { parse } = require("xml-tools/parser");
const xmlText = `<note>
<to>Bill</to>
<from>Tim</from>
</note>
`;
const { cst, lexErrors, parseErrors } = parse(xmlText);
console.log(cst.children["element"][0].children["Name"][0].image); // -> note
