Function xml::escape::escape_str_attribute

pub fn escape_str_attribute(s: &str) -> Cow<str>

Performs escaping of common XML characters inside an attribute value.

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

• < → <
• > → >
• " → "
• ' → '
• & → &

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.
