Function xml::escape::escape_str_pcdata

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

Performs escaping of common XML characters inside PCDATA.

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

• < → <
• & → &

The resulting string is safe to use inside PCDATA sections but NOT inside attribute values.

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