marklogic Working with fn:count, xdmp:estimate and cts:frequency Using fn:count() to get the number of matching documents
Example
The XML document, I will be using throughout the examples is -
<a>
<b>test-value</b>
<d>fragment-d</d>
<c-root>
<d>fragment-d</d>
<e>fragment-e</e>
</c-root>
</a>
The following queries returns the number of documents with value fragment-d for element d -
-
Using a cts:search
fn:count(cts:search(fn:doc(), cts:element-value-query(xs:QName("d"), "fragment-d"))) -
Using XPath
fn:count(fn:doc()[//d="fragment-d"]))
