[Methods] Two kinds of widely known and maturely established OA journal websites—SpringerOpen and PubMed Central were chosen for document type definition(DTD) research of Extensible Markup Language (XML) document. The law of document construction as well as the descriptions of function and design principle of key elements were summarized respectively. [Findings] The two electronic journal standards have common design in structural layout and content classification of document, both frameworks are reasonable and mature. Although distinct differences exist in markup granularity and tag hierarchy between two kinds of documents, each of them has its own characteristic and excellent performance.
