xml-toolkit v1.0.32

node-xml-toolkit

XML parsers (synchronous, streaming), marshaller, SOAP adapters (1.1, 1.2)

Installation

npm i xml-toolkit

Using

• Parsing a small file completely

const fs = require ('fs')
const {XMLParser} = require ('xml-toolkit')

const xml    = fs.readFileSync ('doc.xml')
const parser = new XMLParser  ({...options})

const document = parser.process (xml)

for (const element of document.detach ().children) {
  console.log (element.attributes)
}

• Reading a Record List, streaming mode

const {XMLReader, XMLNode} = require ('xml-toolkit')

const records = new XMLReader ({
  filterElements : 'Record', 
  map            : XMLNode.toObject ({})
}).process (xmlSource)

// ...then:
// await someLoader.load (records)

// ...or
// for await (const record of records) { // pull parser mode

// ...or
// records.on ('error', e => console.log (e))
// records.pipe (nextStream)

// ...or
// records.on ('error', e => console.log (e))
// records.on ('data', record => doSomethingWith (record))

• Getting a Single Element, streaming mode

const {XMLReader, XMLNode} = require ('xml-toolkit')

const data = await new XMLReader ({
  filterElements : 'MyElementName', 
  map            : XMLNode.toObject ({})
}).process (xmlSource).findFirst ()

• Patching XML

const {XMLReader} = require ('xml-toolkit')

let xmlResult = ''; for await (const node of new XMLReader ().process (xmlSource)) xmlResult += 
    node.isCharacters && node.parent.localName === 'ThePlaceHolder' ? id : 
    node.xml

• Serializing an Object According to an XML Schema

const {XMLSchemata} = require ('xml-toolkit')

const data = {ExportDebtRequestsResponse: {	
  "request-data": {
   // ...
  }
}

const xs = new XMLSchemata ('xs.xsd')

const xml = xs.stringify (data)

/* result:
<ns0:ExportDebtRequestsResponse xmlns:ns0="urn:...">
  <ns0:request-data>
    <!-- ... and so on ... -->
*/

• Invoking a SOAP 1.1 or SOAP 1.2 Web Service

const http = require ('http')
const {SOAP11, SOAP12} = require ('xml-toolkit')

const soap = new SOAP11 ('their.wsdl') // or SOAP12

const {method, headers, body} = soap.http ({RequestElementNameOfTheirs: {amount: '0.01'}})

const rq = http.request (endpointURL, {method, headers})
rq.write (body)

• Implementing a SOAP service

const {XMLSchemata, SOAP11, SOAP12, SOAPFault} = require ('xml-toolkit')

const SOAP = SOAP11 // or SOAP12

const xs = new XMLSchemata (`myService.wsdl`)

let body, statusCode; try {  
  body = xs.stringify (myMethod (/*...*/))
  statusCode = 200
}
catch (x) {
  body = new SOAPFault (x)
  statusCode = 500
}

rp.writeHead (statusCode, {
  'Content-Type': SOAP.contentType,
})

const xml = SOAP.message (body)
rp.end (xml)
