In this paper, we discuss the complexity of the validity for positive XPath queries under the presence of DTDs. A given query $p$ is valid under a DTD $D$ if for each XML document conforming to $D$ the answer to $p$ is a nonempty set. Valid XPath queries are useful in XML data mapping settings.
We first show that the validity for the XPath class with only child, descendant-or-self and sibling axes, and wildcard is coNP-hard. Moreover, for the class with child and sibling axes, qualifier and wildcard, the validity is in PTIME. |
