Single Transition Constraint for XML Update Validation

2012 15th International Conference on Network-Based Information Systems, 2012
In this paper, we propose a checking algorithm for dynamic constraint validation during XML updates. Our algorithm is targeted at single transition constraint, which is affected by single node updating. To the best of our knowledge, almost all constraints that have been preserved in the previous XML updates works are for static constraints.

XML Validation for Context-Free Grammars

2006
String expression analysis conservatively approximates the possible string values generated by a program. We consider the validation of a context-free grammar obtained by the analysis against XML schemas and develop two algorithms for deciding inclusion L(G1)⊆L(G2) where G1 is a context-free grammar and G2 is either an XML-grammar or a regular hedge ...

Updating XML Documents without Breaking Their Validity

2008 Third International Conference on Internet and Web Applications and Services, 2008
Over the past few years, XML has become a standard for data representation and data exchange over the web. Although XML data is self-describing, most application domains tend to use document schemas, given as Document Type Definitions (DTDs) or XML-Schemas. An XML document is considered valid if it conforms to the constraints and rules specified in its

Faster XML data validation in a programming language with XML datatypes

ACM SIGPLAN Notices, 2007
EDI-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.

XML Schema Evolution: Incremental Validation and Efficient Document Adaptation

2007
XML Schemas describe the structure of valid documents and can be exploited for improving both the efficiency and effectiveness of queries on valid documents. XML Schemas, however, may need to be updated to adhere to new requirements and to face changes in the application domain.

Updates and Incremental Validation of XML Documents

2004
We 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 ...

Assisting XML Schema Evolution that Preserve Validity

2007
We consider the problem of XML schema evolution preserving the validity of existing documents related to the original schema. The aim of such schema evolution is to fit new needs without revalidating all existing valid XML documents. We propose an approach to assist users to specify schema updates that have no impact on existing document validity.
