Function xml::escape::escape_str_attribute

source · 
pub fn escape_str_attribute(s: &str) -> Cow<'_, str>
Expand description

Performs escaping of common XML characters inside an attribute value.

This function replaces several important markup characters with their entity equivalents:

  • < → &lt;
  • > → &gt;
  • " → &quot;
  • ' → &apos;
  • & → &amp;

The following characters are escaped so that attributes are printed on a single line:

  • \n → &#xA;
  • \r → &#xD;

The resulting string is safe to use inside XML attribute values or in PCDATA sections.

Does not perform allocations if the given string does not contain escapable characters.
