I try to wrap all tables inside my content with a special div container, to make them usable for mobile. I can't wrap the tables, before they are saved within the database of the custom CSS. I managed to get to the content, before it's printed on the page and I need to preg_replace
all the tables there.
I do this, to get all tables:
preg_match_all('/(<table[^>]*>(?:.|\n)*<\/table>)/', $aFile['sContent'], $aMatches);
The problem is to get the inner part (?:.|\\n)*
to match everything that is inside the tags, without matching the ending tag. Right now the expression matches everything, even the ending tag of the table...
Is there a way to exclude the match for the ending tag?
You need to perform a non greedy match: /(<table[^>]*>(?:.|\\n)*?<\\/table>)/
. Note the question mark: ?
.
However, I would use a DOM parser for that:
$doc = new DOMDocument();
$doc->loadHTML($html);
$tables = $doc->getElementsByTagName('table');
foreach($tables as $table) {
$content = $doc->saveHTML($table);
}
While it is already more convenient to use a DOM parser for extracting data from HTML documents, it is definitely the better solution if you are attempting to modify the HTML (as you told).
如果您不想匹配结束标签,可以使用超前模式,
preg_match_all('/(<table[^>]*>(?:.|\n)*(?=<\/table>))/', $aFile['sContent'], $aMatches);
