xmldom-qsa
This is based on xmldom with some minor enhancements.
xmldom-qsa
add querySelector
, querySelectorAll
and match
method to Document
and Element
. And you can write some more methods to these elements by add prototype
methods to Node.
xmldom is a javascript ponyfill to provide the following APIs that are present in modern browsers to other runtimes:
- convert an XML string into a DOM tree
new DOMParser().parseFromString(xml, mimeType) => Document
- create, access and modify a DOM tree
new DOMImplementation().createDocument(...) => Document
- serialize a DOM tree back into an XML string
new XMLSerializer().serializeToString(node) => string
The target runtimes xmldom
supports are currently Node >= v10 (ES5) and Rhino (not tested as part of CI).
When deciding how to fix bugs or implement features, xmldom
tries to stay as close as possible to the various related specifications/standards.
As indicated by the version starting with 0.
, this implementation is not feature complete and some implemented features differ from what the specifications describe.
Issues and PRs for such differences are always welcome, even when they only provide a failing test case.
This project was forked from it's original source in 2019, more details about that transition can be found in the CHANGELOG.
Usage
Install:
npm install xmldom-qsa
Enhancements:
doc.documentElement.querySelector('.clazz');
var Node = require('xmldom-qsa/dom').Node;
Node.prototype.addAttr = function(x,y) { ... }
doc.documentElement.addAttr('x','y');
Example:
const { DOMParser } = require('xmldom-qsa')
const doc = new DOMParser().parseFromString(
'<xml xmlns="a" xmlns:c="./lite">\n' +
'\t<child>test</child>\n' +
'\t<child></child>\n' +
'\t<child/>\n' +
'</xml>',
'text/xml'
)
doc.documentElement.setAttribute('x', 'y')
doc.documentElement.setAttributeNS('./lite', 'c:x', 'y2')
console.info(doc)
const nsAttr = doc.documentElement.getAttributeNS('./lite', 'x')
console.info(nsAttr)
Note: in Typescript ~and ES6~(see #316) you can use the import
approach, as follows:
import { DOMParser } from 'xmldom-qsa'

Specs
The implementation is based on several specifications:
DOM Parsing and Serialization
From the W3C DOM Parsing and Serialization (WD 2016) xmldom
provides an implementation for the interfaces:
DOMParser
XMLSerializer
Note that there are some known deviations between this implementation and the W3 specifications.
Note: The latest version of this spec has the status "Editors Draft", since it is under active development. One major change is that the definition of the DOMParser
interface has been moved to the HTML spec
DOM
The original author claims that xmldom implements [DOM Level 2] in a "fully compatible" way and some parts of [DOM Level 3], but there are not enough tests to prove this. Both Specifications are now superseded by the [DOM Level 4 aka Living standard] wich has a much broader scope than xmldom.
xmldom implements the following interfaces (most constructors are currently not exposed):
Attr
CDATASection
CharacterData
Comment
Document
DocumentFragment
DocumentType
DOMException
(constructor exposed)DOMImplementation
(constructor exposed)Element
Entity
EntityReference
LiveNodeList
NamedNodeMap
Node
(constructor exposed)NodeList
Notation
ProcessingInstruction
Text
more details are available in the (incomplete) API Reference section.
HTML
xmldom does not have any goal of supporting the full spec, but it has some capability to parse, report and serialize things differently when "detecting HTML" (by checking the default namespace). There is an upcoming change to better align the implementation with the latest specs, related to https://github.com/xmldom/xmldom/issues/203.
SAX, XML, XMLNS
xmldom has an own SAX parser implementation to do the actual parsing, which implements some interfaces in alignment with the Java interfaces SAX defines:
XMLReader
DOMHandler
There is an idea/proposal to make it possible to replace it with something else in https://github.com/xmldom/xmldom/issues/55
