An easy way would be to do it using javascript, but a solution using php is possible if you got the tags + contents ont the server side. All you need to do is to parse your tag+content so that you separate the tags from the content and then truncate your content text to 100 characters. Ad the separated tags you still have in a varable and there you go.

Very simple example:

$fulltag_as_string = '<b>This is my text ... blah, blah .. with length more than 100 characters</b>';

$arr = split(">",$fulltag_as_string);
$arr2 = split("<",$fulltag_as_string);
$arr3 = split("<",$arr[1]);

$truncated_text = strlen($arr3[0] > 100) ? substr($arr3[0],0,100) : $arr3[0];

echo $resulting_tag = $arr[0].">".$truncated_text."<".$arr2[2];
