Embodiments of the invention provide systems and methods for searching for elements of a document based on an order priority of attributes of a query expression. According to one embodiment, a method of searching a plurality of objects of a document, such as elements of a DOM document, can comprise generating a query expression with attributes related to a target object of the document. For example, the expression can comprise an XPath expression. The attributes of the query expression can be parsed into one or more attribute groups, each comprising at least one attribute, based on logical operators between the attributes. Each one or more attribute groups of each expression can be weighted and a search can be performed for the target object in the document based on the weighted one or more attribute groups of the query expression.
