How does XPath convert string types?

In XPath, some built-in functions can be used to convert strings into other types.

1. Convert a string to a numeric type: use the number() function. For example, you can convert the string “123” to a number by using number(“123”).
2. To convert a string to a boolean type, use the boolean() function. For example, you can convert the string “true” to a boolean value by using boolean(“true”).
3. Convert a string to a date type using the xs:date() function. For example, to convert the string “2021-01-01” to a date, you can use xs:date(“2021-01-01”).
4. Convert a string to a time type using the xs:time() function. For example, you can convert the string “12:00:00” to a time by using xs:time(“12:00:00”).
5. Convert the string to a datetime type using the xs:dateTime() function. For example, to convert the string “2021-01-01T12:00:00” to a datetime, you can use xs:dateTime(“2021-01-01T12:00:00”).

Please note that the way functions are used in XPath may vary depending on the specific version and implementation of XPath. Therefore, make sure that the XPath engine you are using supports the selected function.
