Class DOMSelector

  org.thymeleaf.dom.DOMSelector

All Implemented Interfaces:

Serializable

public final class DOMSelector
extends Object
implements Serializable

DOM Selectors model selections of subtrees from Thymeleaf DOM trees.

A common use of these selectors is for including fragments of other templates without the need of these other templates having any Thymeleaf code.

DOM Selector syntax is a subset of XPath, including:

• /x means direct children of the current node with name x.
• //x means children of the current node with name x, at any depth.
• x[@z="v"] means elements with name x and an attribute called z with value "v".
• x[@z1="v1" and @z2="v2"] means elements with name x and attributes z1 and z2 with values "v1" and "v2", respectively.
• x[i] means element with name x positioned in number i among its siblings.
• x[@z="v"][i] means elements with name x, attribute z with value "v" and positioned in number i among its siblings that also match this condition.

For example: //div[@id="menu"].

Objects of this class are thread-safe.
