Description
This function operates in almost the same way as the "list" fetch function. The difference is that instead of returning the actual nodes, it returns the count (the number of nodes that were found). The "list_count" function takes the same parameters as the "list" function with some exceptions (sorting, grouping, limit/offset, etc. is not supported). Please refer to the documentation of the "list" function for a detailed description of the parameters.
Examples
Example 1
{def $count=fetch( 'content', 'list_count', hash( 'parent_node_id', 42 ) )} Node number 42 has {$count} number of children.
Outputs the number of nodes that are below node number 42.
