I have a string variable in PHP , its content is:
$var='<SPAN id=1 value=1 name=1> one</SPAN>
<div id=2 value=2 name=2> two</div >';
....
I need a function for surround html attributes with "" i need do this for the all meta-tag
,etc the result should be this:
$var='<SPAN id= "1" value="1" name="1"> one </SPAN>
<div id="2" value="2" name="2" > two</div >';
...
I need replace all =[a-z][A-Z][1-9] for ="[a-z][A-Z][1-9]". I need a regular expresion for preg_replace
You need to wrap it all in single quotes like this:
$myHtml='<SPAN id="1" value="1" name="1"> one </SPAN>
<div id="2" value="2" name="2" > two</div >';
Its is the solution
$var = preg_replace('/(?<==)(\b\w+\b)(?!")(?=[^<]*>)/', '"$1"', $var);
thanks for Ωmega, its works on IE8
use a heredoc which removes the need to escape most anything except $:
$var = <<<EOL
<span id="1" value="1" name="1">one</span>
etc...
EOL
I would run the string through DOMDocument:
$var='<SPAN id=1 value=1 name=1> one</SPAN>
<div id=2 value=2 name=2> two</div >';
// Create a new DOMDocument and load your markup.
$dom = new DOMDocument();
$dom->loadHTML($var);
// DOMDocument adds doctype and <html> and <body> tags if they aren't
// present, so find the contents of the <body> tag (which should be
// your original markup) and dump them back to a string.
$var = $dom->saveHTML($dom->getElementsByTagName('body')->item(0));
// Strip the actual <body> tags DOMDocument appended.
$var = preg_replace('#^<body>\s*(.+?)\s*</body>$#ms', '$1', $var);
// Here $var will be your desired output:
var_dump($var);
Output:
string(85) "<span id="1" value="1" name="1"> one</span>\n<div id="2" value="2" name="2"> two</div>"
Please note that if $var has the potential to contain an actual <body> tag, that modifications will need to be made to this code. I leave that as an exercise to the OP.
" characters, as I showed with the output.
