how can I remove font type from string which is in database and saved with ckeditor? For example:
<div style="font-family: Tahoma; color: Red;">
Foo FOooooo
</div>
I want to remove it or change it to Verdana for example.
I know I can use replace but font names can be different and I know I can use substring method. But is there any easy way to remove it?
Try this simple way by this regex:
capture font-family and color styles:
<div\s+style=\".*?font-family:(?<fontName>\s*[^;\"]*)?.*?color:(?<color>\s*[^;\"]*)?
and your code for replacement:
String inputStr = "<div style=\"font-family: Tahoma; color: Red;\">";
foreach(Match m in Regex.Matches(inputStr, "<div\\s+style=\\\".*?font-family:(?<fontName>\\s*[^;\\\"]*)?.*?color:(?<color>\\s*[^;\\\"]*)?"))
{
inputStr = inputStr.Replace(m.Groups["fontName"].Value, "Vernada").Replace(m.Groups["color"].Value, "Blue");
}
explain:
(?<name> subexpression)Captures the matched subexpression into a named group.
There are two ways, the easy way, just remove the full div style using a "simple" Regex
private static Regex oClearHtmlScript = new Regex(@"<(.|\n)*?>", RegexOptions.Compiled);
public static string StripHTML(string sHtmlKeimeo)
{
if (string.IsNullOrEmpty(sHtmlKeimeo))
return string.Empty;
return oClearHtmlScript.Replace(sHtmlKeimeo, string.Empty);
}
and the hard way, use the Html Agility Pack (or any other similar) to parse the html and direct change the attributes.
