Query Syntax
============
-``( <absolute-path> | <descendant-path> ) [ <leaf-conditions> ] [ <text()-condition> ] [ <ancestor-axis> ]``
+``( <absolute-path> | <descendant-path> ) [ <leaf-conditions> ] [ <text()-condition> ] [ <contains()-condition> ] [ <ancestor-axis> ]``
Each CPS path expression need to start with an 'absolute' or 'descendant' xpath.
@@ -272,6 +272,25 @@ The text()-condition can be added to any CPS path query.
- When querying a leaf value (instead of leaf-list) it is better, more performant to use a text value condition use @<leaf-name> as described above.
- Having '[' token in any index in any list will have a negative impact on this function.
+contains()-condition
+--------------------
+
+**Syntax**: ``<cps-path> '[' 'contains' '(' '<leaf-name>','<string-value>' ')' ']'?``
+ - ``cps-path``: Any CPS path query.
+ - ``leaf-name``: The name of the leaf which value needs to be compared.
+ - ``string-value``: The required value of the leaf element as a string wrapped in quotation marks (U+0022) or apostrophes (U+0027). This will still match integer values.
+
+**Examples**
+ - ``//categories[contains(@name,'Sci')]``
+ - ``//books[contains(@title,'Space')]``
+
+**Limitations**
+ - Only leaves can be used, leaf-list are not supported.
+ - Leaf names are not validated so ``contains() condition`` with invalid leaf names will silently be ignored.
+
+**Notes**
+ - contains condition is case sensitive.
