### tokenize
```
array[string] tokenize(string source, string pattern)
```
Returns an array of strings formed by splitting the source string into an array of strings, separated by substrings that match the given regular expression pattern.
It is a type error if either argument is not a string.
### Example
```cpp
#include <iostream>
#include <jsoncons/json.hpp>
#include <jsoncons_ext/jsonpath/jsonpath.hpp>
using json = jsoncons::json;
namespace jsonpath = jsoncons::jsonpath;
int main()
{
std::string data = R"(
{
"books":
[
{
"title" : "A Wild Sheep Chase",
"author" : "Haruki Murakami"
},
{
"title" : "Almost Transparent Blue",
"author" : "Ryu Murakami"
},
{
"title" : "The Quiet American",
"author" : "Graham Greene"
}
]
}
)";
json j = json::parse(data);
// All titles whose author's last name is 'Murakami'
std::string expr = R"($.books[?(tokenize(@.author,'\\s+')[-1] == 'Murakami')].title)";
json result = jsonpath::json_query(j, expr);
std::cout << pretty_print(result) << "\n\n";
}
```
Output:
```json
[
"A Wild Sheep Chase",
"Almost Transparent Blue"
]
```
