How to change the first letter to lowercase using XPath or XSLT

I am using wso2esb-4.8.1.

I want to change my first request letter to lowercase. I get the request parameters as follows:

 <property name="Methodname" expression="//name/text()" scope="default" type="STRING"/>

So I get names like

GetDetails, CallQuerys, ChangeService ...

While I want to change all names like this:

getDetails, callQuerys, changeService ...

If I wanted the upper or lower case of the whole name, I could use the XPath fn:upper-case()and functions fn:lower-case(), but my requirement is different.

How can I change all first letters only in lower case?

Is this possible with XPath or XSLT?

XPath 1.0:

<property name="Methodname" scope="default" type="STRING" 
          expression="concat(translate(substring(//name/text(), 1, 1), 
                                       'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 
                                       'abcdefghijklmnopqrstuvwxyz'), 
                             substring(//name/text(), 2))"/>

XPath 2.0:

<property name="Methodname" scope="default" type="STRING" 
          expression="concat(lower-case(substring(//name/text(), 1, 1)), 
                             substring(//name/text(), 2))"/>
