xml - Xquery append text to tag values depending of the element type

Question

I need to get the values of some elements and then some text needs to be added depending on the element, for example:

<elementType>a</elementType> 
<otherElementType>b</otherElementType> 
<elementType>c</elementType> 
<elementType>d</elementType>

$doc//*[self::elementType or self::otherElementType]/string()

"a"
"b"
"c"
"d"

this returns the values but I don′t know how to get the values like this:

"a is an elementType"
"b is an otherElementType"
"c is an elementType"
"d is an elementType"

Answer 1

Use:

//*[self::elementType or self::otherElementType]
              /concat(., ' is a ', name(), '
')

When this expression is evaluated against the following XML document (the provided malformed fragment -- corrected):

<t>
    <elementType>a</elementType>
    <otherElementType>b</otherElementType>
    <elementType>c</elementType>
    <elementType>d</elementType>
</t>

The wanted, correct result is produced:

a is a elementType
 b is a otherElementType
 c is a elementType
 d is a elementType
