Validation of XML Document Updates Based on XML Schema in XML Databases

2003
We 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.

Checking potential validity of XML documents

Proceedings of the 7th International Workshop on the Web and Databases: colocated with ACM SIGMOD/PODS 2004, 2004
The 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.

Validating XML Documents

2017
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?

Incremental Validation of XML Documents

2002
We 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.

Validating XML Constraints Using Automata

2009 Eighth IEEE/ACIS International Conference on Computer and Information Science, 2009
In this paper, we address the problem of validating constraints in XML. In particular, we concentrate on the three commonly discussed types of constraints, functional dependencies, keys and foreign keys. Unranked bottom-up tree automata can be used to validate XML documents against a schema, and we further extend the automata to validate constraints ...

Incremental Validation of XML Document Based on Simplified XML Element Sequence Pattern

2010 Seventh Web Information Systems and Applications Conference, 2010
With XML becoming the de facto standard for representing and exchanging data on the Internet, the problem of validation of XML data when updated has attracted more and more attentions. The traditional brute-force validation processes the entire updated XML document from scratch, which is less efficient.

Validating XML with Schematron

2004
Early 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.

Validity-Sensitive Querying of XML Databases

2006
We 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 ...

Retrieving valid matches for XML keyword search

Proceedings of the 2009 ACM symposium on Applied Computing, 2009
Adapting keyword search to XML data has been attractive recently, generalized as XML Keyword Search (XKS). Its fundamental task is to retrieve meaningful and concise result for the given keyword query, and [1] is the latest work which returns the fragments rooted at the SLCA (Smallest LCA - Lowest Common Ancestor) nodes. To guarantee the fragments only

XML Template Functional and Multivalued Dependencies Validation

International Journal of Cooperative Information Systems, 2019
In this paper, we present two types of XML semantic constraints, namely the XML Template Functional Dependencies (XTFDs) and the XML Template Multivalued Dependencies (XTMVDs), which are both defined over the finite XML files that have no mixed contents. Essentially they specify that if a pattern of nodes appears in a finite XML file that has no mixed
