The document contains some white space that delimits various aspects of the XML syntax.

When the white space is part of the XML syntax, it is discarded by XML parsers and not passed on to processing applications.

The majority of HESA returns are made using XML: The specification of each of our records begins with the data model.

A data model (sometimes known as an Entity Relationship Model) defines the entities covered by the specification and the relationship between the entities. An element is identified using tags (defined with 'pointy brackets') and each element must have a start tag and an end tag.

It’s inevitable that different XML parsers make different interpretations of the standards.

This leads to some fuzzy behavior where white space is concerned.

The first exception to the significant white space rule deals with attribute values.

The XML parser uses a set of rules to normalize attribute values.

Entities have attributes; for example, gender identity is an attribute of a student. To refer to specific fields, our documentation uses the format Entity. Each tag contains the element name and the end tag also contains a / character. For example, this Student entity has attributes of name and date of birth: What is schema error?
