This package simply tells you whether or not a string matches the Name or QName productions in the XML Namespaces specification. We use it for implementing the validate algorithm in jsdom, but you can use it for whatever you want.
This package's main module exports two functions, name() and qname(). Both take a string and return a boolean indicating whether or not the string matches the relevant production.
"use strict": const xnv = require("xml-name-validator"); // Will return true xnv.name("x"); xnv.name(":"); xnv.name("a:0"); xnv.name("a:b:c"); // Will return false xnv.name("\\"); xnv.name("'"); xnv.name("0"); xnv.name("a!"); // Will return true xnv.qname("x"); xnv.qname("a0"); xnv.qname("a:b"); // Will return false xnv.qname(":a"); xnv.qname(":b"); xnv.qname("a:b:c"); xnv.qname("a:0");
