We generally use an asterisk (*) while writing XPaths. This is called a Wildcard character.
An asterisk in XPath may represent any node or attribute name of XML or DOM. A node is a tag in XML document. When we do not bother about node or attribute name we can use an asterisk. For example:-
//span -> Only span node/s
//* -> Any node/s
//div//* -> Any child node of any parent node “div”
An asterisk can help us with attribute names as well. For example:-
//input[@*=’demo’] -> Any “input” node who contains an attribute value as “demo” for any attribute.
//a[@*] -> Any ‘a’ node who contains any attribute
//a[contains(@*,’demo’)] -> Any ‘a’ node whose any attribute value contains “demo”.
