Tree Construction Tests
Each file containing tree construction tests consists of any number of tests separated by two newlines (LF) and a single newline before the end of the file. For instance:
[TEST]LF
LF
[TEST]LF
LF
[TEST]LF
Where [TEST] is the following format:
Each test must begin with a string "#data" followed by a newline (LF). All subsequent lines until a line that says "#errors" are the test data and must be passed to the system being tested unchanged, except with the final newline (on the last line) removed.
Then there must be a line that says "#errors". It must be followed by one line per parse error that a conformant checker would return. It doesn't matter what those lines are, although they can't be "#document-fragment", "#document", "#script-off", "#script-on", or empty, the only thing that matters is that there be the right number of parse errors.
Then there *may* be a line that says "#document-fragment", which must be followed by a newline (LF), followed by a string of characters that indicates the context element, followed by a newline (LF). If the string of characters starts with "svg ", the context element is in the SVG namespace and the substring after "svg " is the local name. If the string of characters starts with "math ", the context element is in the MathML namespace and the substring after "math " is the local name. Otherwise, the context element is in the HTML namespace and the string is the local name. If this line is present the "#data" must be parsed using the HTML fragment parsing algorithm with the context element as context.
Then there *may* be a line that says "#script-off" or "#script-on". If a line that says "#script-off" is present, the parser must set the scripting flag to disabled. If a line that says "#script-on" is present, it must set it to enabled. Otherwise, the test should be run in both modes.
Then there must be a line that says "#document", which must be followed by a dump of the tree of the parsed DOM. Each node must be represented by a single line. Each line must start with "| ", followed by two spaces per parent node that the node has before the root document node.
- Element nodes must be represented by a "
<" then the tag name string ">", and all the attributes must be given, sorted lexicographically by UTF-16 code unit according to their attribute name string, on subsequent lines, as if they were children of the element node. - Attribute nodes must have the attribute name string, then an "=" sign, then the attribute value in double quotes (").
- Text nodes must be the string, in double quotes. Newlines aren't escaped.
- Comments must be "
<" then "!--" then the data then "-->". - DOCTYPEs must be "
<!DOCTYPE" then the name then if either of the system id or public id is non-empty a space, public id in double-quotes, another space an the system id in double-quotes, and then in any case ">". - Processing instructions must be "
<?", then the target, then a space, then the data and then ">". (The HTML parser cannot emit processing instructions, but scripts can, and the WebVTT to DOM rules can emit them.) - Template contents are represented by the string "content" with the children below it.
The tag name string is the local name prefixed by a namespace designator. For the HTML namespace, the namespace designator is the empty string, i.e. there's no prefix. For the SVG namespace, the namespace designator is "svg ". For the MathML namespace, the namespace designator is "math ".
The attribute name string is the local name prefixed by a namespace designator. For no namespace, the namespace designator is the empty string, i.e. there's no prefix. For the XLink namespace, the namespace designator is "xlink ". For the XML namespace, the namespace designator is "xml ". For the XMLNS namespace, the namespace designator is "xmlns ". Note the difference between "xlink:href" which is an attribute in no namespace with the local name "xlink:href" and "xlink href" which is an attribute in the xlink namespace with the local name "href".
If there is also a "#document-fragment" the bit following "#document" must be a representation of the HTML fragment serialization for the context element given by "#document-fragment".
For example:
#data
<p>One<p>Two
#errors
3: Missing document type declaration
#document
| <html>
| <head>
| <body>
| <p>
| "One"
| <p>
| "Two"
