CDATA is a str subclass for character data which is serialized as a CDATA section. It can be used as the text or the tail of an element. The content of a CDATA section is parsed as ordinary character data by default. If insert_cdata is true, TreeBuilder adds it to the tree as a CDATA string: as the text or the tail of an element if it is not set yet, and otherwise in a new element with the tag None. A section does not share the place with what follows it, so it is moved to such an element if character data or another section follows it. The C implementation supports this too: pyexpat exposes XML_SetCdataSectionHandler in its capsule, and _set_factories takes the CDATA type as the third argument.

An alternative to #156742:
CDATAis astrsubclass for character data which is serialized as a CDATA section, instead of a factory of special elements. It can be used as the text or the tail of an element:The content of a CDATA section is parsed as ordinary character data by default. If insert_cdata is true,
TreeBuilderadds it to the tree as aCDATAstring: as the text or the tail of an element if it is not set yet, and otherwise in a new element with the tagNone. A section does not share the place with what follows it, so it is moved to such an element if character data or another section follows it.Since the content is character data, it is a part of the inner text returned by
itertext()and by the"text"serialization method, without any change inElement.pyexpat exposes
XML_SetCdataSectionHandlerin its capsule, and_set_factories()takes theCDATAtype as the third argument, so the C implementation supports this too.
