I am trying to replace an xml from variable got from data weave into another data weave xml but I am getting xml with special chars as below, when the variable is replaced in the transform instead of getting '<' .
<pol:convictionCode>AC24</pol:convictionCode>
<pol:date>28012019</pol:date>
<pol:banLength>00</pol:banLength>
I am trying as below code but its not correct, getting error (org.mule.api.MessagingException: Execution of the expression).I also need to replace
with ''. Not sure how to replace both of them in one go. Highly appreciate any help.
payload.replaceAll("\\<","<")

I am facing an issue with JSON extract using JSON_EXTRACT_PATH_TEXT in redshift
I have two separate JSON columns
One containing the modems the customer is using and the other one containing the recharge details
{"Mnfcr": "Technicolor","Model_Name":"Technicolor ABC1243","Smart_Modem":"Y"}
For the above, I have no issue extracting the Model_name using JSON_EXTRACT_PATH_TEXT(COLUMN_NAME, 'Model_Name') as model_name
[{"Date":"2021-12-24 21:42:01","Amt":50.00}]
This one is causing me trouble. I used the same method above and it did not work. it gave me the below error
ERROR: JSON parsing error Detail: ----------------------------------------------- error: JSON parsing error code: 8001 context: invalid json object [{"Date":"2021-07-03 17:12:16","Amt":50.00
Can I please get assistance on how to extract this using the json_extract_path_text?
One other method I have found and it worked was to use regexp_substring.
This second string is a json array (square braces), not an object (curly brackets). The array contains a single element which is an object. So you need to extract the object from the array before using JSON_EXTRACT_PATH_TEXT().
The junction for this is JSON_EXTRACT_ARRAY_ELEMENT_TEXT().
Putting this all together we get:
JSON_EXTRACT_PATH_TEXT(
JSON_EXTRACT_ARRAY_ELEMENT_TEXT( <column>, 0)
, 'Amt')
you can use json_extract_path_text like below example
json_extract_path_text(json_columnName, json_keyName) = compareValue
for more you can refer this article

I am setting a Variable in Grafana.
I want to create a Query, that only returns a subset of the labels with value app the ones I want to return are those ending in dev
My Query so far, returns all of the labels with value app successfully. However, I have been unable to successfully filter the values so that only a-dev b-dev and c-dev are returned.
How do I successfully apply regex (or alternative) to this query so that I can see the desired values?
Any help on this would be greatly appreciated!
I eventually figured out what I needed to do. Originally I was trying to use | to run regex on the results from label_values.
However, this format worked:
label_values({app=~".*-dev$"}, app)
and returned only a-dev b-dev c-dev as expected.
I have the following .check on my returned body: (I changed the values for security reasons but the structure is the same)
.exec(http("Get ids")
.post("GetIds")
.body(ElFileBody("json/getIds.json")).asJson
.check(jsonPath("$...Types..[?(#.Type == 'web')].id").findAll.saveAs("IDLlist"))
But the transaction fails with "Gettting findAll.exists extraction crashed: end of input expected when trying to extract values from a returned body"
Gatling prints the body of the failed transaction, when I take the exact body that the transaction had just failed on to http://jsonpath.com/ and
evaluate the jsonpath that had just failed, I get good results with no issues. This means that the returned body is correct and that the jsonpath is also correct.
What is the issue then?
Thanks to Stephane from the Gatling forum, I found that $..Files[?(#.Format == 'DASH_Web')].URL is correct works instead of the variation that I had.
Since http://jsonpath.com/ was able to extract the correct path using my original syntax, I think its important to note that Gatling jsonpath is much more conservative in its syntax.
It seems your JSON path syntax is wrong --> "$...Types..[?(#.Type == 'web')].id"
Try using JSONPath Online Evaluator -- http://jsonpath.com/ to find correct json syntax
I have one of jmeter User defined variable as a "comma separated value" - ${countries} = IN,US,CA,ALL .
(I was first trying to get it as a list/array - [IN,US,CA,ALL] )
I want to use the variable to test a web service - GET /${country}/info . IS it possible using ForEach controller or Loop controller ?
Only thing is that I want to save it or read it as IN,US,..,ALL and use it in the request path.
Thanks
The CSV should be as per the format mentioned in the image attached.

CSV config is a red herring, you don't need it.
You can use a regular expression extractor to split up the variable into another variable (eg MyVar), using something like:
(.+?)[,\n]
This is trying to match each item before a , or newline. It will place the values in variables like MyVar_1, MyVar_2, etc. This is as close to an array as JMeter understands natively.
You can then loop on the contents of the matches using MyVar_matchNr, and MyVar_1 to MyVar_n (you will need to use __V() function to access the 'array' contents.
I'm trying to analyze how postgreSQL parse a query, and after some postgreSQL source code tracing with embedding printf() here and there, I've known that the query will be parsed into raw parse tree with raw_parser, which located in file parser.c.
The strange thing is, I've already embedded a printf() dummy in the raw_parser, and after re-installing the postgreSQL and execute a query, my printf() dummy is not printed to the screen!
Can anybody please help me, where I went wrong?
Thanks in advance :D
if you use printf(stderr, "...."), then you can find result in server log. Don't forget - you are not work with server directly. For debugging purposes there are a elog function - it's like printf for client application:
elog(NOTICE, "some text");
a format string is same like printf's format - but you must to remember, PostgreSQL uses a different formats than glibc - so you can to show only integer or float variables. String variables uses different format than is C zero finished string.
