A lightweight XML validator in the browser using libxml2-wasm with support for recursive XSD imports/includes/redefines via a MapInputProvider.

🧰 Usage Example

`ts
import { useWorker, validateXml } from "xml-xsd-validator-browser";

function test1() {
const xmlText =


;
validateXml(xmlText)
.catch(err => {
console.log(err) // returning array contains object has name:"XMLValidateError"
})
}
test1()

async function test2() {
const xmlText =



;
const mainSchemaUrl = "https://ferdisap.github.io/schema/s1000d/S1000D_5-0/xml_schema_flat/appliccrossreftable.xsd";

const { validate, terminate } = useWorker()
validate(xmlText, mainSchemaUrl)
// never get resolved if the file is valid
.then(response => {
const { id, status, bags } = response;
console.log(id, status, bags) // returning array contains object has name:"XMLValidateError"
})
.catch(response => {
console.log(response)
terminate()
})

}
test2()
