0.9.0-beta.4

Fixed

  • Security: Prevent inserting DOM nodes when they are not well-formed CVE-2022-39353 In case such a DOM would be created, the part that is not well-formed will be transformed into text nodes, in which xml specific characters like < and > are encoded accordingly. In the upcoming version 0.9.0 those text nodes will no longer be added and an error will be thrown instead. This change can break your code, if you relied on this behavior, e.g. multiple root elements in the past. We consider it more important to align with the specs that we want to be aligned with, considering the potential security issues that might derive from people not being aware of the difference in behavior. Related Spec: https://dom.spec.whatwg.org/#concept-node-ensure-pre-insertion-validity

0.9.0-beta.1

Fixed

Only use HTML rules if mimeType matches #338, fixes #203

In the living specs for parsing XML and HTML, that this library is trying to implement, there is a distinction between the different types of documents being parsed: There are quite some rules that are different for parsing, constructing and serializing XML vs HTML documents.

So far xmldom was always "detecting" whether "the HTML rules should be applied" by looking at the current namespace. So from the first time an the HTML default namespace (http://www.w3.org/1999/xhtml) was found, every node was treated as being part of an HTML document. This misconception is the root cause for quite some reported bugs.

BREAKING CHANGE: HTML rules are no longer applied just because of the namespace, but require the mimeType argument passed to DOMParser.parseFromString(source, mimeType) to match 'text/html'. Doing so implies all rules for handling casing for tag and attribute names when parsing, creation of nodes and searching nodes.

BREAKING CHANGE: Correct the return type of DOMParser.parseFromString to Document | undefined. In case of parsing errors it was always possible that "the returned Document" has not been created. In case you are using Typescript you now need to handle those cases.

BREAKING CHANGE: The instance property DOMParser.options is no longer available, instead use the individual readonly property per option (assign, domHandler, errorHandler, normalizeLineEndings, locator, xmlns). Those also provides the default value if the option was not passed. The 'locator' option is now just a boolean (default remains true).

BREAKING CHANGE: The following methods no longer allow a (non spec compliant) boolean argument to toggle "HTML rules":

  • XMLSerializer.serializeToString
  • Node.toString
  • Document.toString

The following interfaces have been implemented: DOMImplementation now implements all methods defined in the DOM spec, but not all of the behavior is implemented (see docstring):

  • createDocument creates an "XML Document" (prototype: Document, property type is 'xml')
  • createHTMLDocument creates an "HTML Document" (type/prototype: Document, property type is 'html').
    • when no argument is passed or the first argument is a string, the basic nodes for an HTML structure are created, as specified
    • when the first argument is false no child nodes are created

Document now has two new readonly properties as specified in the DOM spec:

  • contentType which is the mime-type that was used to create the document
  • type which is either the string literal 'xml' or 'html'

MIME_TYPE (/lib/conventions.js):

  • hasDefaultHTMLNamespace test if the provided string is one of the miem types that implies the default HTML namespace: text/html or application/xhtml+xml

Thank you @weiwu-zhang for your contributions

0.8.0

Fixed

  • Normalize all line endings according to XML specs 1.0 and 1.1
    BREAKING CHANGE: Certain combination of line break characters are normalized to a single \n before parsing takes place and will no longer be preserved.
  • XMLSerializer: Preserve whitespace character references #284 / #310
    BREAKING CHANGE: If you relied on the not spec compliant preservation of literal \t, \n or \r in attribute values. To preserve those you will have to create XML that instead contains the correct numerical (or hexadecimal) equivalent (e.g. &#x9;, &#xA;, &#xD;).
  • Drop deprecated exports DOMImplementation and XMLSerializer from lib/dom-parser.js #53 / #309 BREAKING CHANGE: Use the one provided by the main package export.
  • dom: Remove all links as part of removeChild #343 / #355

0.5.0

Commits

Fixes

  • Avoid misinterpretation of malicious XML input - GHSA-h6q6-9hqw-rwfv (CVE-2021-21366)

    • Improve error reporting; throw on duplicate attribute
      BREAKING CHANGE: It is currently not clear how to consistently deal with duplicate attributes, so it's also safer for our users to fail when detecting them. It's possible to configure the DOMParser.errorHandler before parsing, to handle those errors differently.

      To accomplish this and also be able to verify it in tests I needed to

      • create a new Error type ParseError and export it
      • Throw ParseError from errorHandler.fatalError and prevent those from being caught in XMLReader.
      • export DOMHandler constructor as __DOMHandler

    • Preserve quotes in DOCTYPE declaration Since the only purpose of parsing the DOCTYPE is to be able to restore it when serializing, we decided that it would be best to leave the parsed publicId and systemId as is, including any quotes. BREAKING CHANGE: If somebody relies on the actual unquoted values of those ids, they will need to take care of either single or double quotes and the right escaping. (Without this change this would not have been possible because the SAX parser already dropped the information about the quotes that have been used in the source.)

The patch versions (v0.1.29 - v0.1.31) that have been released on the v0.1.x branch, to reflect the changed maintainers, are branched off from v0.1.27 so they don't include the breaking changes introduced in xmldom-alpha@v0.1.28:

Maintainer changes

After the last commit to the original repository https://github.com/jindw/xmldom on the 9th of May 2017, the first commit to https://github.com/xmldom/xmldom is from the 19th of December 2019. The fork has been announced in the original repository on the 2nd of March 2020.

The versions listed below have been published to one or both of the following packages:

It is currently not planned to continue publishing the xmldom-alpha package.

The new maintainers did not invest time to understand changes that led to the last xmldom version 0.1.27 published by the original maintainer, but consider it the basis for their work. A timeline of all the changes that happened from that version until 0.3.0 is available in xmldom#62. Any related questions should be asked there.
