I need to load and read an XML file using JavaScript.

The following code works fine in Firefox, IE and Opera:

function loadXMLDoc(dname) {

  var xmlDoc



  // Internet Explorer

  try {

    xmlDoc = new ActiveXObject('Microsoft.XMLDOM')

  }

  catch (e) {

    // Firefox, Opera, etc.

    try {

      xmlDoc = document.implementation.createDocument('', '', null)

    }

    catch (e) {

      alert(e.message)

    }

  }



  try {

    xmlDoc.async = false

    xmlDoc.load(dname)

    return xmlDoc

  }

  catch (e) {

    alert(e.message)

  }



  return null

}

But executing this code in Chrome gives me this error:

Object# has no method load

Legacy Code

document.implementation.createDocument does not work on Chrome and Safari.

Use XMLHttpRequest instead when possible:

function loadXMLSync(url) {

  try {

    // Prefer XMLHttpRequest when available

    var xhr = new XMLHttpRequest()

    xhr.open('GET', url, false)

    xhr.setRequestHeader('Content-Type', 'text/xml')

    xhr.send()



    return xhr.responseXML

  }

  catch (e) {

    // XMLHttpRequest not available, fallback on ActiveXObject

    try {

      var activex = new ActiveXObject('Microsoft.XMLDOM')

      activex.async = false

      activex.load(url)



      return activex

    }

    catch (e) {

      // Neither XMLHttpRequest or ActiveXObject are available

      return undefined

    }

  }

}

Modern Browsers

If you're targeting modern browsers (> IE6), just use XMLHttpRequest:

function loadXMLSync(url) {

  var xhr = new XMLHttpRequest()



  xhr.open('GET', url, false)

  xhr.setRequestHeader('Content-Type', 'text/xml')

  xhr.send()



  return xhr.responseXML

}
