The following functions are available:

xml_convert($str[, $protect_all = FALSE])

Parameters:

• $str (string) – the text string to convert
• $protect_all (bool) – Whether to protect all content that looks like a potential entity instead of just numbered entities, e.g. &foo;

Returns:

XML-converted string

Return type:

string

Takes a string as input and converts the following reserved XML characters to entities:

• Ampersands: &
• Less than and greater than characters: < >
• Single and double quotes: ‘ “
• Dashes: -

This function ignores ampersands if they are part of existing numbered character entities, e.g. &#123;. Example:

$string = '<p>Here is a paragraph & an entity (&#123;).</p>';
$string = xml_convert($string);
echo $string;

outputs:

<p>Here is a paragraph & an entity ({).</p>
