We have WMB 6.

I am trying to store an xml tree in cache using the Cache data nodes.

To store the data, I used the following ESQL as input to a CachePut node:
Declare data Char;
Set data = CAST(ASBITSTREAM(InputRoot.XML.CacheTable OPTIONS FolderBitStream) AS CHARACTER CCSID 437 ENCODING 546);
Set OutputRoot.XML.go.key = 'LogCacheJobTable';
Set OutputRoot.XML.go.data.(XML.CDataSection) = data;

I then tried to use a CacheReplay node to retrieve the cache. The data looked like this (via trace node) after the CacheReplay:
(0x01000010):XML = (
..(0x01000000):go = (
....(0x01000000):results = (
......(0x01000000):LogCacheJobTable = (
........(0x02000000): = '<CacheTable><JobData>...</JobData></CacheTable>'

I try to parse it using the following code, and it always evaluates CDataSection as NULL:
Set OutputRoot.XML.go.results.LogCacheJobTable.(XML.AsisElementContent) = InputRoot.XML.go.results.LogCacheJobTable.(XML.CDataSection);


Any help converting the CData section of the cached data back to an XML tree would be much appreciated.

Thanks!!!!!!!!!!

I changed it to

Declare xmlData Char;
Set xmlData = InputRoot.XML.go.results.LogCacheJobTable;
Set OutputRoot.XML.go.results.LogCacheJobTable.(XML.AsisElementContent) = xmlData;

This picked up the data, but it is still being stored as string content.
(0x01000010):XML = (
..(0x01000000):go = (
...(0x01000000):results = (
......(0x01000000):LogCacheJobTable = (
......(0x06000028): = '<CacheTable><JobData>..</JobData></CacheTable>'

How do I get the character data converted to an xml tree?

Thanks!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

This worked:

-- Create some base elements
CREATE FIELD OutputRoot.XML.go;
CREATE FIELD OutputRoot.XML.go.results;

-- Convert CData in cache to XML tree
CREATE LASTCHILD OF OutputRoot.XML.go.results DOMAIN ('XML')
PARSE(InputRoot.XML.go.results.LogCacheJobTable, 546, 437);


Thanks!!!!!

The XML domain has been deprecated since version 2.1.

Please use only XMLNS or XMLNSC with version 6.
