XML document types can include XQL queries for document recognition and XQL queries for extracting document attributes.
Trading Networks does not read the entire content of large XML documents into memory to perform XQL queries; instead, it reads only the number of bytes you specify on the
tn.xml.xqlThreshold into memory. The XQL queries, therefore, must match nodes in the first portion of the document. If the XQL queries identify nodes in the portion that is not in memory, the query fails, and
Trading Networks cannot match the document type to the document or extract document attributes.
