I'm a fresher and new to IIB.
I came across PARSE() function and I have few doubts on that.
The statement thats used in the application is:
PARSE(xPath, inEncoding, inCCSID, 'BLOB', 'XMLNSC')
When I refered IIB site, found the syntax as:
|--PARSE--(--BitStreamExpression--+------------------------------+--)--|
| .-<<-----------------------. |
| V | |
'---+-ENCODING--expression-+-+-'
+-CCSID--expression----+
+-SET--expression------+
+-TYPE--expression-----+
+-FORMAT--expression---+
'-Options--------------'
which mentions When you use the PARSE clause, specify a scalar value containing the bit stream that is to be parsed for BitStreamExpression.
But nowhere in the code, the xpath is converted to bitstream using ASBITSTREAM but it still works fine.
Could anyone please explain why this happens and how the function works ? |

Actually it's a block which contains Cdata.
I want to parse that cdata as xml and fetch the field values.
Eg: <input>
<outerblock>
<innerblock>
<![CDATA[another xml data]]>
</innerblock>
</outerblock>
</input> |
