    To match such a tag

    It is widely accepted that using regexes to parse general html is bad form. If your html is much more complicated than the example given, then you should use an XML parser instead.

    Further discussion in this famous SO question. RegEx match open tags except XHTML self-contained tags.

    If you want to parse the content properly, then download xml_io_tools and use

    doc = xml_read('test.html')
doc.b.FONT.CONTENT

    If you want to stick with regexes, then use ilya's answer, but with one of the regexes from the linked answer, e.g.,

    str = '<HTML><b><FONT color="red" size="3">Hello</FONT></b></HTML>';
rx = '<(?:"[^"]*"['"]*|'[^']*'['"]*|[^'">])+>';
regexprep(str, rx, '')

    My solution is:

    >> str='<HTML><b><FONT color="red" size="3">Hello</FONT></b></HTML>';
>> regexprep(str, '<.*?>','')

ans =

    Since you mentioned that you want to extract "hello" from the above html (say filename.html) file, you can use the following in MATLAB:

    doc = xmlread('filename.html'); content = doc.item(0).getTextContent

    Hope this helps!
