Method Detail

forHTMLTag

public static java.lang.String forHTMLTag(java.lang.String aTagFragment)

Replace characters having special meaning inside HTML tags with their escaped equivalents, using character entities such as '&'.

The escaped characters are :

• <
• >
• "
• '
• \
• &

This method ensures that arbitrary text appearing inside a tag does not "confuse" the tag. For example, HREF='Blah.do?Page=1&Sort=ASC' does not comply with strict HTML because of the ampersand, and should be changed to HREF='Blah.do?Page=1&Sort=ASC'. This is commonly seen in building query strings. (In JSTL, the c:url tag performs this task automatically.)
