Display Formats (continued)
XML (eXtensible Markup Language) is another tagged format. XML is generally used for displaying and manipulating data in software applications. However, we recommend that you use the E-Utilities for downloading sets of PubMed records for manipulation and display in other systems.
Use PMID List to create a plain text list of PubMed identifiers (PMIDs) that can be used to efficiently retrieve batches of PubMed records in the future. See more about using PMIDs.
