JSON Validator - Validate and Format JSON

Skip to content Starting with JSONBuddy 4.6, you can add custom formats for the JSON validator as regular expressions using a simple configuration file. The JSON editor has got two new commands to give you easy access to this new functionality:Commands for JSON custom formatsHow to add and use custom formats?Use the “Open JSON validator custom formats” command to open the JSON configuration file for custom formats directly in JSONBuddy. This is a standard JSON document and the default one will be loaded in the editor. You can then add your own entries to the JSON array for your validation tasks. Please note that you can also replace some existing formats which are already provided by the JSON validator of JSONBuddy. A user-defined format will override the built-in definition.The standard configuration has the following entry:[ { "format": "my-custom-format", "regex": "^[a-z, A-Z, /]+$" }]As you can see all you need to do is to provide two simple strings to add a custom format. The identifier of the new format and a (valid) regular expression. After you have finished adding your new entries you simply save the configuration file and activate the new formats with the “Reload JSON validator custom formats” command. All open JSON documents are immediately validated using the new format definitions.You can also see the names of your own formats on editing your JSON data in the editor:library example with custom format definitionThe “library” example, which is part of the standard installation, also uses a custom format. Just check it out and play around with different regular expressions.

3.18.0 • Public • Published 4 years ago ReadmeCode Beta0 Dependencies2,913 Dependents149 Versionsfast-xml-parser Validate XML, Parse XML to JS/JSON and vice versa, or parse XML to Nimn rapidly without C/C++ based libraries and no callbackTo cover expenses, we're planning to launch FXP Enterprise edition in parallel. Watch it for further updates, if you're interested. UsersList of some applications/projects using Fast XML Parser. (Raise an issue to submit yours) Main FeaturesValidate XML data syntacticallyTransform XML to JSON or NimnTransform JSON back to XMLWorks with node packages, in browser, and in CLI (press try me button above for demo)Faster than any pure JS implementation.It can handle big files (tested up to 100mb).Various options are available to customize the transformationYou can parse CDATA as a separate property.You can prefix attributes or group them to a separate property. Or they can be ignored from the result completely.You can parse tag's or attribute's value to primitive type: string, integer, float, hexadecimal, or boolean. And can optionally decode for HTML char.You can remove namespace from tag or attribute name while parsingIt supports boolean attributes, if configured.How to useTo use it in NPM package install it first$npm install fast-xml-parser or using yarn $yarn add fast-xml-parserTo use it from a CLI install it globally with the -g option.$npm install fast-xml-parser -gTo use it on a webpage include it from a CDNXML to JSONvar jsonObj = parser.parse(xmlData [,options] );var parser = require('fast-xml-parser');var he = require('he');var options = { attributeNamePrefix : "@_", attrNodeName: "attr", //default is 'false' textNodeName : "#text", ignoreAttributes : true, ignoreNameSpace : false, allowBooleanAttributes : false, parseNodeValue : true, parseAttributeValue : false, trimValues: true, cdataTagName: "__cdata", //default is 'false' cdataPositionChar: "\\c", parseTrueNumberOnly: false, arrayMode: false, //"strict" attrValueProcessor: (val, attrName) => he.decode(val, {isAttributeValue: true}),//default is a=>a tagValueProcessor : (val, tagName) => he.decode(val), //default is a=>a stopNodes: ["parse-me-as-string"]};if( parser.validate(xmlData) === true) { //optional (it'll return an object in case it's not valid) var jsonObj = parser.parse(xmlData,options);}// Intermediate objvar tObj = parser.getTraversalObj(xmlData,options);var jsonObj = parser.convertToJson(tObj,options);As you can notice in the above code, validator is not embedded with in the parser and expected to be called separately. However, you can pass true or validation options as 3rd parameter to the parser to trigger validator internally. It is same as above example.try{ var jsonObj = parser.parse(xmlData,options, true);}catch(error){ console.log(error.message)}Validator returns the following object in case of error;{ err: { code: code, msg: message, line: lineNumber, },};Note: he library is used in this example OPTIONS :attributeNamePrefix : prepend given string to attribute name for identificationattrNodeName: (Valid name) Group all the attributes as properties of given name.ignoreAttributes : Ignore attributes to be parsed.ignoreNameSpace : Remove namespace string from tag and attribute names.allowBooleanAttributes : a tag can have attributes without any valueparseNodeValue : Parse the value.
