## Loading this Helper

This helper is loaded using the following code

    $this->load->helper('xml');

## Available Functions

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:

      &lt;p&gt;Here is a paragraph &amp; an entity (&#123;).&lt;/p&gt;
