you have two options to access that data: httprequest.responsetext – returns the server response as a string of text httprequest.responsexml – returns the response as an xmldocument object you can traverse with javascript dom functions note that the steps above are valid only if you used an asynchronous request (the third parameter of open() was unspecified or set to true).
...now let's try the responsexml property.
... then in alertcontents(), we need to replace the line alert(httprequest.responsetext); with: var xmldoc = httprequest.responsexml; var root_node = xmldoc.getelementsbytagname('root').item(0); alert(root_node.firstchild.data); this code takes the xmldocument object given by responsexml and uses dom methods to access some of the data contained in the xml document.

Object.prototype.toString() - JavaScript
the following code defines the dog object type and creates thedog, an object of type dog: function dog(name, breed, color, sex) { this.name = name; this.breed = breed; this.color = color; this.sex = sex; } thedog = new dog('gabby', 'lab', 'chocolate', 'female'); if you call the tostring() method on this custom object, it returns the default value inherited from object: thedog.tostring(); // returns [object object] the following code creates and assigns dogtostring() to override the default tostring() method...
...this function generates a string containing the name, breed, color, and sex of the object, in the form "property = value;".
... dog.prototype.tostring = function dogtostring() { const ret = 'dog ' + this.name + ' is a ' + this.sex + ' ' + this.color + ' ' + this.breed; return ret; } or, using es6 template strings: dog.prototype.tostring = function dogtostring() { return `dog ${this.name} is a ${this.sex} ${this.color} ${this.breed}`; } with the preceding code in place, any time thedog is used in a string context, javascript automatically calls the dogtostring() function, which returns the following string: "dog gabby is a female chocolate lab" using tostring() to detect object class tostring() can be used with every object and (by default) allows you to get its class.

xmlhttprequest.responsexml read only returns a document containing the response to the request, or null if the request was unsuccessful, has not yet been sent, or cannot be parsed as xml or html.

Parsing and serializing XML - Developer guides
"error while parsing" : odom.documentelement.nodename); parsing url-addressable resources into dom trees using xmlhttprequest here is sample code that reads and parses a url-addressable xml file into a dom tree: var xhr = new xmlhttprequest(); xhr.onload = function() { dump(xhr.responsexml.documentelement.nodename); } xhr.onerror = function() { dump("error while getting xml."); } xhr.open("get", "example.xml"); xhr.responsetype = "document"; xhr.send(); the value returned in the xhr object's responsexml field is a document constructed by parsing the xml.

The HTML autocomplete attribute - HTML: Hypertext Markup Language
"sex" a gender identity (such as "female", "fa'afafine", "male"), as freeform text without newlines.

Working with objects - JavaScript
for example, suppose you define an object called person as follows: function person(name, age, sex) { this.name = name; this.age = age; this.sex = sex; } and then instantiate two new person objects as follows: var rand = new person('rand mckinnon', 33, 'm'); var ken = new person('ken jones', 39, 'm'); then, you can rewrite the definition of car to include an owner property that takes a person object, as follows: function car(make, model, year, owner) { this.make = make; this.mo...

Intl.DateTimeFormat.prototype.formatToParts() - JavaScript
chinese and tibetan calendars, for example, use a 60-year sexagenary cycle of named years.

Object.isFrozen() - JavaScript
object.isextensible(frozen); // === false // also by definition, a frozen object is sealed.

Object.isSealed() - JavaScript
object.isextensible(sealed); // === false // a sealed object might be frozen, // but it doesn't have to be.

Object.prototype.__proto__ - JavaScript
the object must be extensible according to object.isextensible(): if it is not, a typeerror is thrown.

Object.setPrototypeOf() - JavaScript
description throws a typeerror exception if the object whose [[prototype]] is to be modified is non-extensible according to object.isextensible().

Object.prototype.toSource() - JavaScript
examples using tosource() the following code defines the dog object type and creates thedog, an object of type dog: function dog(name, breed, color, sex) { this.name = name; this.breed = breed; this.color = color; this.sex = sex; } thedog = new dog('gabby', 'lab', 'chocolate', 'female'); calling the tosource() method of thedog displays the javascript source that defines the object: thedog.tosource(); // returns ({name:"gabby", breed:"lab", color:"chocolate", sex:"female"}) specifications not part of any standard.

Object - JavaScript
object.isextensible() determines if extending of an object is allowed.

handler.preventExtensions() - JavaScript
interceptions this trap can intercept these operations: object.preventextensions() reflect.preventextensions() invariants if the following invariants are violated, the proxy will throw a typeerror: object.preventextensions(proxy) only returns true if object.isextensible(proxy) is false.

Proxy() constructor - JavaScript
handler.isextensible() a trap for object.isextensible.

Reflect - JavaScript
reflect.isextensible(target) same as object.isextensible().

XML: Extensible Markup Language
xml:basexml:base is like the html baseelement but can specify the base uri per element as well as the entire document.

Introduction to using XPath in JavaScript - XPath
var req = new xmlhttprequest(); req.open("get", "chrome://yourextension/content/peopledb.xml", false); req.send(null); var xmldoc = req.responsexml; var nsresolver = xmldoc.creatensresolver( xmldoc.ownerdocument == null ?

XPath snippets - XPath
if you are using xmlhttprequest to read a local or remote xml file into a dom tree (as described in parsing and serializing xml), the first argument to evaluatexpath() should be req.responsexml.
