XpathElement Class Reference

Detailed Description

All parsing logic (condition, position, attributes) is encapsulated in the constructor so that callers (e.g. XmlDb::getNodeIdsByXpath) never need to call XpathParser helpers again — they only read pre-computed properties.

The parser itself remains SQL-agnostic; the caller is responsible for assembling SQL fragments from the pre-parsed data.
