Function Documentation

std::string CPPCMS_API cppcms::util::escape

(

std::string const &

s

)

Escape string for inclusion in HTML page, i.e.

• < - &lt;
• > - &gt;
• & - &amp;
• " - &quot;
• &#39; - &#39;

Note, this function does not deal with encodings, so it's up to you to provide valid text encoding

void CPPCMS_API cppcms::util::escape	(	char const *	begin,
		char const *	end,
		std::ostream &	output
	)

Escape string for inclusion in HTML page, i.e.

• < - &lt;
• > - &gt;
• & - &amp;
• " - &quot;
• &#39; - &#39;

int CPPCMS_API cppcms::util::escape	(	char const *	begin,
		char const *	end,
		std::streambuf &	output
	)

Escape string for inclusion in HTML page, i.e.

• < - &lt;
• > - &gt;
• & - &amp;
