    TABLE OF CONTENTS
    SYNOPSIS
    DESCRIPTION
    COMMANDS
    EXAMPLES

Returns the contents of html with certain characters that are special in HTML replaced with an escape code. This allows text displayed in a webpage that might otherwise be interpreted as containing HTML markup instructions to be interpreted as literal characters to be displayed. Specifically: ns_quotehtml > becomes &

: > becomes &gt;
: " becomes &amp;
: ' becomes &#39;
: " becomes &#34;

All other characters are unmodified in the output.

% ns_quotehtml "Hello World!" Hello World!

% ns_quotehtml "The <STRONG> tag is used to indicate strongly emphasized text." The &lt;STRONG&gt; tag is used to indicate strongly emphasized text.

% ns_quotehtml {<span class="foo">} &lt;span class=&#34;foo&#34;&gt;

NOTES The set of characters that are substituted and their replacements may be different in previous versions of NaviServer. For example, NaviServer 2.x does not escape single or double-quotes.
