XPath 문법

Syntax Meaning
tag Selects all child elements with the given tag. For example, spam selects all child elements named spam, and spam/egg selects all grandchildren named egg in all children named spam.
* Selects all child elements. For example, */egg selects all grandchildren named egg.
. Selects the current node. This is mostly useful at the beginning of the path, to indicate that it’s a relative path.
// Selects all subelements, on all levels beneath the current element. For example, .//eggselects all egg elements in the entire tree.
.. Selects the parent element.
[@attrib] Selects all elements that have the given attribute.
[@attrib='value'] Selects all elements for which the given attribute has the given value. The value cannot contain quotes.
[tag] Selects all elements that have a child named tag. Only immediate children are supported.
[position] Selects all elements that are located at the given position. The position can be either an integer (1 is the first position), the expression last() (for the last position), or a position relative to the last position (e.g. last()-1).
