will help you (Disclaimer: I am not familiar with WSO2, only with XML/XPath.)
It seems to me that your problem is due to the default namespace in your XML input:

<messageCollection xmlns="http://services.core.solution.com/ds/queue">

//*:message[last()]/*:createddate

//*[local-name() = 'message'][last()]/*[local-name() = 'createddate']

<args>
   <arg evaluator="xml" expression="//ns:message[last()]/ns:createddate" xmlns:ns="http://services.core.solution.com/ds/queue"/>
</args>

XPath query returns null Tag : xpath , By : Ryuken Date : March 29 2020, 07:55 AM wish help you to fix your issue It seems that	isn't direct child of current item. To select descendant that isn't direct child you can use double slashes (//) : `item.SelectSingleNode(".//td")` `item.SelectSingleNode("th/td")`
WSO2 ESB - Xpath expression returns null value on SOAP response Tag : xpath , By : BinaryBoy Date : March 29 2020, 07:55 AM I hope this helps you . The nodes return and mobile does not belong to ns2 namespace, try with //return/mobile/text()
WSO2 CEP - SIDDHI max function in time window returns null Tag : wso2 , By : user186435 Date : March 29 2020, 07:55 AM around this issue for letting us know the inconsistent behavior, based on SQL it should return null. We have made fixes such that avg(), min(), max(), and sum() to return null when no events in the table[1]. Do use default() or ifThenElse() with "is null" to convert null to extected default value if needed.
Getting XML node using XPath returns null Tag : chash , By : Tony Siu Date : March 29 2020, 07:55 AM should help you out You must specify the exact namespaces. Also you have to specify namespace prefixes for all elements in the XPath. `manager.AddNamespace("nsDoc", "http://www.unece.org/cefact/namespaces/StandardBusinessDocumentHeader"); manager.AddNamespace("nsInvoice", "urn:oasis:names:specification:ubl:schema:xsd:Invoice-2"); manager.AddNamespace("cbc", "urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2"); string query = "/nsDoc:StandardBusinessDocument/nsInvoice:Invoice/cbc:ID";`
Xpath response always returns null Tag : python , By : Ian Badcoe Date : March 29 2020, 07:55 AM like below fixes the issue You can't always trust in the "Inspect element" in devtools because it shows the final HTML, after it was rendered by Javascript. One tip is copy the price, say "1850", open the page source code with right click "View Page Source" (in Firefox, something like this in Chrome) and search for the price on it to see where the source of the information is. You will find this tag with useful information: `<meta class="product-data" data-designer-name="Chloe" data-designer-id="122" data-analytics-key="Roy Day small leather and suede shoulder bag" data-pid="1100692" data-breadcrumb-names="Bags / Shoulder Bags / Cross Body" data-breadcrumb-keys="Bags / Shoulder_Bags / Cross_Body" data-breadcrumb-ids="1282 / 1335 / 6012" data-sold-out="false" data-price-full="185000" data-price="185000" />` `response.css('meta.product-data::attr(data-price)').extract_first()` `response.xpath('//meta[@class="product-data"]/@data-price').extract_first()`
