You can do this with theregexp column script. Granted, regexp is not the best way to parse HTML, but it will prob work fine for most pages.
This is the config you would need
{
"name": "HtmlTitle",
"label": "HtmlTitle",
"header": "",
"type": "text",
"defwidth": "30",
"justify": "left",
"infotiponly": false,
"maxstars": "5",
"datetimeformat": "yyyy-mm-dd",
"nogroup": false,
"grouporder": "",
"sorting": "normal",
"regexp": "<\\s*?title\\s*?>(.*?)</\\s*?title\\s*?>",
"inputItemProperty": "contents",
"firstValid": true,
"output": "$1",
"filter": "*.html",
"graphLowerColor": "",
"graphUpperColor": "",
"graphColorThreshhold": ""
}
