Vitaliy,
Because it's in XQilla you can just use it. If there are issues it is not available for Oracle-based support but those working on XQilla will likely investigate.
Here's an example that just returns the XML mapping of some simple JSON:
dbxml> query xqilla:parse-json('{"menu": {
"id": "file",
"value": "File",
"popup": {
"menuitem": [
{"value": "New", "onclick": "CreateNewDoc()"},
{"value": "Open", "onclick": "OpenDoc()"},
{"value": "Close", "onclick": "CloseDoc()"}
1 objects returned for eager expression 'xqilla:parse-json('{"menu": {
"id": "file",
"value": "File",
"popup": {
"menuitem": [
{"value": "New", "onclick": "CreateNewDoc()"},
{"value": "Open", "onclick": "OpenDoc()"},
{"value": "Close", "onclick": "CloseDoc()"}
dbxml> print
<json type="object"><pair name="menu" type="object"><pair name="id" type="string">file</pair><pair name="value" type="string">File</pair><pair name="popup" type="object"><pair name="menuitem" type="array"><item type="object"><pair name="value" type="string">New</pair><pair name="onclick" type="string">CreateNewDoc()</pair></item><item type="object"><pair name="value" type="string">Open</pair><pair name="onclick" type="string">OpenDoc()</pair></item><item type="object"><pair name="value" type="string">Close</pair><pair name="onclick" type="string">CloseDoc()</pair></item></pair></pair></pair></json>
Here's an example that queries the parsed JSON:
dbxml> query xqilla:parse-json('{"menu": {
"id": "file",
"value": "File",
"popup": {
"menuitem": [
{"value": "New", "onclick": "CreateNewDoc()"},
{"value": "Open", "onclick": "OpenDoc()"},
{"value": "Close", "onclick": "CloseDoc()"}
}}')//pair[.="CreateNewDoc()"]
1 objects returned for eager expression 'xqilla:parse-json('{"menu": {
"id": "file",
"value": "File",
"popup": {
"menuitem": [
{"value": "New", "onclick": "CreateNewDoc()"},
{"value": "Open", "onclick": "OpenDoc()"},
{"value": "Close", "onclick": "CloseDoc()"}
}}')//pair[.="CreateNewDoc()"]'
dbxml> print
<pair name="onclick" type="string">CreateNewDoc()</pair>
Have fun -- it's quite experimental at this stage.
