Updates and Incremental Validation of XML Documents
International Workshop/Symposium on Database Programming Languages, 2004We consider the incremental validation of updates on XML documents. When a valid XML document (i.e., one satisfying some constraints) is updated, it has to be verified that the new document still conforms to the imposed constraints. Incremental validation of updates leads to significant savings on computing time when compared to brute-force validation ...

Validation of XML Document Updates Based on XML Schema in XML Databases
2003We study the validation of XML documents when they are updated in XML databases. An XML document can be verified by checking against an XML Schema, which contains structure and type information of XML documents. However, most of XML database systems just validate the whole XML document, but can not validate parts of it.

Incremental Validation of XML Documents
2002We investigate the incremental validation of XML documents with respect to DTDs and XML Schemas, under updates consisting of element tag renamings, insertions and deletions. DTDs are modeled as extended context-free grammars and XML Schemas are abstracted as "specialized DTDs", allowing to decouple element types from element tags.

Approximate Validity of XML Streaming Data
2008 The Ninth International Conference on Web-Age Information Management, 2008We present a SAX implementation of the statistical embedding associated with XML data, introduced in [1], [2], which allows to efficiently decide eps-validity to any DTD or Schema, for the Edit Distance with Moves. It associates a generalized k-gram to unranked labelled trees (with k = 1/epsiv) from which any regular property can be approximately ...

Validating XML with Schematron
2004Early on in this book, you learned that XML is a meta-markup language, a specification of the syntax that a wide variety of markup languages all follow. You also learned the difference between well-formed XML documents, which follow the XML syntax, and valid XML documents, which adhere to the rules laid down by a particular markup language.

However, in many real-world cases this assumption may not be true. For example, a purchase order application might be accepting orders from various customers in XML format. What is the guarantee that each submitted order adheres to the agreed-on XML structure? What if somebody deviates from the agreed-on structure?

Checking potential validity of XML documents
Proceedings of the 7th International Workshop on the Web and Databases: colocated with ACM SIGMOD/PODS 2004, 2004The process of creation of document-centric XML documents often starts with a prepared textual content, into which the editor introduces markup. In such situations, intermediate XML is almost never valid with respect to the DTD/Schema used for the encoding.

Faster XML data validation in a programming language with XML datatypes
ACM SIGPLAN Notices, 2007EDI-C is a programming language used in B2B (EDI, WebServices) applications. It is possible to declare XML variables in the language. XML variables are declared in a way similar to structures in C and C++. These variables are accessed through dot-notation. Validation information (facets) can also be declared.

Validity-Sensitive Querying of XML Databases
2006We consider the problem of querying XML documents which are not valid with respect to given DTDs. We propose a framework for measuring the invalidity of XML documents and compactly representing minimal repairing scenarios. Furthermore, we present a validity-sensitive method of querying XML documents, which extracts more information from invalid XML ...
