Examples of com.caucho.xpath.pattern.AbstractPattern

com.caucho.xpath.pattern.AbstractPattern
A node selection pattern. AbstractPatterns represent compiled XPath node selectors. They can be used to find nodes, select nodes, and test if a node matches a pattern.
There are two types of patterns: select patterns and match patterns.
Select patterns match a node relative to another node. find and select use select patterns.
Match patterns match a node in isolation. isMatch uses match patterns.
