Detailed Description

Provides DOMTraverser visitors that fix template-induced interrupted table cell parsing by recombining table cells and/or reparsing table cell content as attributes.

• stripDoubleTDs
• handleTableCellTemplates

Constructor & Destructor Documentation

__construct()

Wikimedia\Parsoid\Wt2Html\PP\Handlers\TableFixups::__construct

(

Env

$env

)

Set up some helper objects for reparseTemplatedAttributes

Actually the regular tokenizer, but we'll use tokenizeTableCellAttributes only.

Member Function Documentation

reparseTemplatedAttributes()

Wikimedia\Parsoid\Wt2Html\PP\Handlers\TableFixups::reparseTemplatedAttributes	(	Frame	$frame,
		Element	$cell,
		?Element	$templateWrapper )

T46498, second part of T52603.

Handle wikitext like

{|
|{{nom|Bar}}
|}

where nom expands to style="foo" class="bar"|Bar. The attributes are tokenized and stripped from the table contents.

This method works well for the templates documented in https://en.wikipedia.org/wiki/Template:Table_cell_templates/doc

Nevertheless, there are some limitations:

• We assume that attributes don't contain wiki markup (apart from <nowiki>) and end up in text or nowiki nodes.
• Only a single table cell is produced / opened by the template that contains the attributes. This limitation could be lifted with more aggressive re-parsing if really needed in practice.
• There is only a single transclusion in the table cell content. This limitation can be lifted with more advanced data-mw construction.

Parameters

Frame	$frame
Element	$cell	known to be

/

Parameters

?Element

$templateWrapper

FIXME: These checks are insufficient. Previous rounds of table fixups might have created this cell without any templated content (the while loop in handleTableCellTemplates). Till we figure out a reliable test for this, we'll reparse attributes always.

// This DOM pass is trying to bridge broken parses across // template boundaries. so, if templates aren't involved, // no reason to reparse. if ( count( $attributishContent['transclusions'] ) === 0 && !WTUtils::fromEncapsulatedContent( $cell ) ) { return; }

stripDoubleTDs()

Wikimedia\Parsoid\Wt2Html\PP\Handlers\TableFixups::stripDoubleTDs	(	Element	$node,
		Frame	$frame )

DOM visitor that strips the double td for this test case:

|{{1x|{{!}} Foo}}
