Question

I was trying to parse the style attribute of a simple <font> tag and convert it back to simple html attributes. For instance, I have this string <font style="font-family:tahoma;font-size:24px;color:#9900CC;"> and I’d like to somehow convert it to <font size="24" color="#9900CC" face="tahoma"> I know this can be done with regex but I have no idea how?

thanks

So here is the simplest solution I’ve made so far its a dirty solution but it works like a charm:

static public String convertCSSFonttoHTML(String css)
{

    List<List<String>> allFontTags = regexFindMultiStrings("<font[^>]*(style=['\"][^'\"]+['\"])[^>]*>", css);
    String allAttributes = "";

    for(int y=0; y<allFontTags.size(); y++)
    {
        String style = allFontTags.get(y).get(0);
        String size = regexFindString("font-size:([^0-9]+)", style);
        String color = regexFindString("color:([^;]+);", style);
        String face = regexFindString("font-family:([^;]+)", style);

        if(!size.isEmpty())
             allAttributes += "size=\""+size+"\" ";

        if(!color.isEmpty())
             allAttributes += "color=\"" + color + "\" ";

        if(!size.isEmpty())
             allAttributes += "face=\""+face+"\"";



        //do replacements to the first occurance
        css = css.replaceFirst(style, allAttributes);

        //empty atts
        allAttributes = "";
    }

    //Log.e("Regex", css);


    return css;

}
