XmlParser

A tolerant HTML/XML parser: unlike JsonParser, it never throws on malformed markup -- an invalid tag or mismatched closing tag just logs a warning (aParser::addError, not overridden here) and is preserved as literal text, so parsing always completes (matching how browsers handle real-world HTML). Comments are recognized and dropped; content inside $ignoreNodesIn tags (script/style/...) is NOT parsed as markup.

XmlParser::Nodes('<div class="a">Hello <b>World</b></div>'); // an XmlNodes tree

Index

	TOKEN_COMMENT_END	Internal token id marking the end of a `-->` comment.
	TOKEN_COMMENT_START	Internal token id marking the start of a `<!--` comment (`createTokenizer`/`process`).
	ignoreNodesIn	Tag names whose content is never parsed as markup (kept as raw text).
	createTokenizer()
	Nodes($xml, $root) static	Parse HTML/XML into a node tree.
	process($opts)

Constants2

TOKEN_COMMENT_END

Internal token id marking the end of a --> comment.

const TOKEN_COMMENT_END = 10002

TOKEN_COMMENT_START

Internal token id marking the start of a <!-- comment (createTokenizer/process).

const TOKEN_COMMENT_START = 10001

Properties1

ignoreNodesIn

Tag names whose content is never parsed as markup (kept as raw text).

array $ignoreNodesIn = ['script', 'style', 'textarea', 'code', 'fn', 'path']

Type: array

Methods3

createTokenizer()

XmlParser.php:38

function createTokenizer(): MMO\core\helpers\Tokenizer

See: aParser::createTokenizer -- recognizes  comments, and tags (TagDomain) with quoted attribute values.

returns

Tokenizer

Nodes($xml, $root)

staticXmlParser.php:33

Parse HTML/XML into a node tree.

static function Nodes($xml, ?MMO\core\helpers\XmlNodes $root = null): MMO\core\helpers\XmlNodes

$xml
$root = null	null \| XmlNodes	if given, parsed nodes are appended into it instead of a fresh tree (useful to parse a fragment into an existing document).
returns	XmlNodes

process($opts)

XmlParser.php:50

protected function process(array $opts = []): mixed

See: aParser::process -- entry point: walks the token stream building a tree of, XmlNode elements (attached under $opts['root'], a fresh XmlNodes if not given).

$opts = []	array
returns	mixed	the root node tree.

Methods	Declared by	Description
`addError($token, $message, $context)`	aParser	Record a parse error/warning: logs it (`tLogEmitter::warning`) and appends it to
`alert($message, $context)`	aModule	Action must be taken immediately.
`backtraces($message, $context)`	aModule	Force-log a message at INFO level together with a full stack trace/memory snapshot (`iLogLevel::BACKTRACE`), bypassing the verbosity mask entirely (any non-zero verbosity is enough to trigger it).
`Configure($config)`	aModule	Merge $config into this module's configuration in the shared `Configuration`.
`critical($message, $context)`	aModule	Critical conditions. No-op if CRITICAL is currently filtered out by the verbosity mask.
`debug($message, $context)`	aModule	Detailed debug information.
`debugName()`	aModule	Human-readable identifier used as the default `{origin}` in this instance's log messages.
`DefaultConfig()`	aModule	The config a module starts from before anything loaded via `Configuration` is merged in.
`emergency($message, $context)`	aModule	System is unusable. No-op if EMERGENCY is currently filtered out by the verbosity mask.
`error($message, $context)`	aModule	Runtime errors that do not require immediate action but should typically be logged and monitored.
`getErrors()`	aParser
`getTokenizer()`	aParser
`getVerbosity()`	aModule
`hasErrors()`	aParser
`info($message, $context)`	aModule	Interesting events. No-op if INFO is currently filtered out by the verbosity mask.
`Instantiate($config)`	aModule	(Re)create the shared instance immediately, configured with $config merged into the class's existing config.
`isLocked()`	aParser
`IsShared()`	aModule
`log($level, $message, $context)`	aModule	Logs with an arbitrary level.
`notice($message, $context)`	aModule	Normal but significant events.
`offsetExists($key)`	aModule	\ArrayAccess::offsetExists -- tells whether $key is a declared property at all, regardless of whether it is currently readable/writable through array access.
`offsetGet($key)`	aModule	\ArrayAccess::offsetGet -- reads a property directly, unless it has a `#[Serialize(serialize: 'methodName')]` attribute, in which case that zero-argument method is called instead (e.g.
`offsetSet($key, $value)`	aModule	\ArrayAccess::offsetSet -- sets a property directly, unless it has a `#[Serialize(unserialize: 'methodName')]` attribute, in which case that method is called with $value instead (e.g.
`offsetUnset($key)`	aModule	\ArrayAccess::offsetUnset -- equivalent to `$module[$key] = null`.
`parse($text, $opts)`	aParser	Parse $text: resets `getErrors`, (re)builds/reuses the tokenizer, runs `process`, then always clears the tokenizer's tokens from memory (even if process() throws).
`serialize($path, $serializer)`	aModule	\MMO\core\interfaces\iSerializable::serialize -- exports every property (via
`setVerbosity($verb)`	aModule	Set the current verbosity mask, replacing whatever it was before.
`Shared()`	aModule	Get the shared instance, creating (and configuring) it on first call.
`testVerbosity($level)`	aModule	Test whether a given level (or set of levels) is currently enabled by this instance's verbosity mask.
`traitUnshare($serialize)`	aModule	Remove the shared instance, so the next `Shared()` call creates a fresh one.
`unserialize($data, $path, $instances)`	aModule	\MMO\core\interfaces\iSerializable::unserialize -- merges $data onto `DefaultConfig`, runs it through the (possibly overridden) constructor, then applies each resulting value to its property (via
`Unshare($serialize)`	aModule	Like `tSingleton::Unshare`, but also disconnects this module's instance from every event it was listening to (via `Event::DisconnectListeners`) before dropping it.
`warning($message, $context)`	aModule	Exceptional occurrences that are not errors.
`__construct($config)`	aModule	protected constructor, so it is not possible to do `new Module(...)` called by the serialization process just before being injected with data.
