The expression /*/text() returns a node set (XPath 1.0) or sequence of nodes (XPath 2.0) consisting of all the text nodes that are immediate children of the document element. It does not include text nodes that are children of other elements, i.e. given a document

<root>foo<child>bar</child>baz</root>

/*/text() would be a set of two text nodes, one containing the text foo and the other containing baz.

The count function returns the number of nodes in a node set (XPath 1.0)/items in a sequence (XPath 2.0). In XPath 1.0 all numbers are treated as double precision floating point, in XPath 2.0 count has the more specific return type of xs:integer.
