Raymond created CAMEL-23381:
-------------------------------
Summary: simple language - Set the resulttype directly on xpath
and jsonpath
Key: CAMEL-23381
URL: https://issues.apache.org/jira/browse/CAMEL-23381
Project: Camel
Issue Type: Improvement
Components: camel-core
Reporter: Raymond
By default jsonpath and xpath return an object:
{{}}
{code:java}
jsonpath(exp)
jsonpath(input,exp)
xpath(exp)
xpath(input,exp){code}
Mostly you want to explicitly get the type (string, int, boolean). Since 4.18.x
this has become a bit more flexible, and developers can do something like this:
{code:java}
$price1 := ${xpath(//food[name='food1']/price/text())} ~> ${convertTo(int)};
{code}
It would be however convenient to set the resultType directly on the function:
{code:java}
jsonpath(exp, resultType)
jsonpath(input,exp, resultType)
xpath(exp, resultType)
xpath(input,exp, resultType)
{code}
{{Setting the resultType is in aligment with the rest of the Simple language. }}
{{Sidenote:}}
{{{}I also saw some other ways to define to type in other languages
like:{}}}{{{}{}}}
* {{int:${xpath(//food/price)}}}
* {{${xpath(//food/price).toInteger()}}}
* {{${xpath(...) as int}}}
One of the above maybe a bit more elegant, but is of course not the standard
syntax until now.
