问题
I have a class that generates some html (form elements and table elements), but this class returns all the html in one line.
So I am trying to use tidy to beautify the code (indent the code, put line breaks, etc), the only problem I am having is that's also generating the tags I don't want.
Here is the code:
tidy_parse_string(
$table->getHtml(),
array(
'DocType' => 'omit',
'indent' => true,
'indent-spaces' => 4,
'wrap' => 0
)
);
The only way I have found to remove the extra html tags is by adding a str_replace, something like this:
str_replace(array('<html>','</html>','<body>','</body>','<head>','</head>','<title>','</title>'),'', code);
Which works, but I was really hopping there would be a way to tell tidy to just beautify the code and not insert the extra code.
回答1:
Try the show-body-only option.
e.g.
$s = '<form method="post" action="?"><table><tr><td><input tpye="submit"></table>';
echo tidy_parse_string($s, array('show-body-only'=>true, 'indent'=>true));
prints
<form method="post" action="?">
<table>
<tr>
<td>
<input tpye="submit">
</td>
</tr>
</table>
</form>
(string has been repaired and indented but no html/body wrapper added). Can be combined with the output-xhtml option which in this case would also add the slash for the empty input element.
