This function is relatively easy:

lcX = "http://www.mysite.com/&lt;font-color=red&gt;&lt;b&gt;mytext-2010&lt;/b&gt;&lt;/font&gt;/mytext-p-1473.html?name=Chocolate%20Lover%27s%20Special%20%28USA%29"

? URL2TXT(lcX)

FUNCTION URL2TXT
LPARAMETERS lcURL

LOCAL lcResult
lcResult = lcURL

DO WHILE "%" $ lcResult
  lcResult = STUFF(lcResult, AT("%", lcResult), 3, HEX2TXT(SUBSTR(lcResult, AT("%", lcResult)+1, 2)))
ENDDO

lcResult = STRTRAN(lcResult, "&"+"lt;", "<")
lcResult = STRTRAN(lcResult, "&"+"gt;", ">")
lcResult = STRTRAN(lcResult, "&"+"amp;", "&")
lcResult = STRTRAN(lcResult, "&"+"quot;", '"')

RETURN lcResult

FUNCTION HEX2TXT
LPARAMETERS lcHex

LOCAL lcStr
lcStr = "0h" + lcHex

RETURN "" + &lcStr
