Hi all. I'm trying to remove the <font face> tag but leave the data that is found within the tag intact. So far im using

story = Regex.Replace(story, "</?(font face)[^>]*>", string.Empty, RegexOptions.IgnoreCase) 

this works well, but it doesnt remove the </font> tag. how can i also remove the closing tag? thanks

Hi,

Since you require "face" in the pattern, a pure "font" tag won't be found.

This won't really work, anyway, because you'd need to find the exact end tag. That's not possible with regular expressions (if the elements can be nested).

The clean solution to this would be to use a HTML parser and actually remove the elements. Otherwise you'll have to mix the regex with a kind of tag counter to find the matching end tag (which is really not that pretty).

i see, what about leaving the font tags but simply removing anything found in "face" ?

eg

<font face="arial">test</font> BECOMES.. <font>test</font> 

edit... done using

story = Regex.Replace(story, "font face=[^>]*", "font", RegexOptions.IgnoreCase)

Well, then I don't get what you're trying to do.

I thought you wanted to remove the tags of every "font" element with a "face" attribute? If you remove the attributes, you can no longer distinguish between "normal" font elements and those with a "face" attribute.

the font family is standardised in the css so i didnt want any <font face> tags in the body over-riding this, but i wanted to keep font size and color tags

Just add .replace("</font>", "") to the end of that line so its:

 story = Regex.Replace(story, "</?(font face)[^>]*>", string.Empty, RegexOptions.IgnoreCase).replace("</font>", "")

Good?

You're confusing the words. "font" is the HTML element, and "face", "color" etc. are attributes of this element.

So if I understand you correctly now, you want to remove the "face" attribute from any "font" element. The cleanest way for this would really be to use a DOM parser. Alternatively, you could try this pattern:

(<font[^>]+)face="[^"]"([^>]*>)

(You might need to escape the double quotes)

And then concatenate both matching groups to build the replacement string.

However, this will only find the attribute syntax
face="..."
It won't find face='...' or something. If you want that, too, the regular expression will become more and more complex.

sorry another question regarding something similar.

if i wanted to remove all instances of "font-family" e.g.

font-family:'Calibri','sans-serif';

i can use the following:

story = Regex.Replace(story, "font-family[^>]*", """", RegexOptions.IgnoreCase) 

but if the line was

 line-height:115%;font-family:'Calibri','sans-serif';font-size:12pt 

it would become

line-height:115%; 

i'd need to leave the font-size in tact and only remove the font-family attribute
