But only get Nodeset0, expected value from xml response.

I checked xpath on http://xpather.com/ and seems it's should work.

Hi,

I think your XPath query is right and returns effectively a node (as we hint it in the logs).

Could you try to use the string XPath function to convert this node to a string ?

POST https://test_api
Content-Type: application/xml; charset=utf-8
file,test.xml;

HTTP/2 200
[Captures]
tr_id: xpath "string(//Envelope/Body/OTA_AirAvailRS/@TransactionIdentifier)"

So instead of:

tr_id: xpath "//Envelope/Body/OTA_AirAvailRS/@TransactionIdentifier"

Use

tr_id: xpath "string(//Envelope/Body/OTA_AirAvailRS/@TransactionIdentifier)"

We don't convert nodes returned from query because you can also evaluate tests on collections (like count etc...)

If your capture is still not working, could you send the complete XML body?

Regards,

With string I just get empty value

* Captures
* tr_id: 
* 

I reduced a little xml body,

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><soap:Body xmlns:ns1="http://www.opentravel.org/OTA/2003/05"><ns1:OTA_AirAvailRS EchoToken="11868765275150-1300257934" PrimaryLangID="en-us" RetransmissionIndicator="false" SequenceNmbr="1" TransactionIdentifier="TID$16459590516432752971.demo2144" Version="2006.01"></ns1:OTA_AirAvailRS></soap:Body></soap:Envelope>

Thanks,
I can see now why the capture is not working, it's because of the Xml Namespace in the xml body and the way we treat it.
For the moment, you can rewrite your capture like this:

POST https://test_api
Content-Type: application/xml; charset=utf-8
file,test.xml;

HTTP/2 200
[Captures]
tr_id: xpath "string(//*[name()='Envelope']/*[name()='Body']/*[name()='OTA_AirAvailRS']/@TransactionIdentifier)"

Not ideal, we are going to look if we can improve Xml Namespace support.

Can you test it with this new xpath expression ?

[balroggg]

Same results as before(empty id). 😢

[balroggg]

//*[name()='soap:Envelope'] - find something by xpather
//*[name()='Envelope'] - not
maybe xpath not valid?

[balroggg]

This works for me thanks!

tr_id: xpath "string(//*[name()='soap:Envelope']/*[name()='soap:Body']/*[name()='ns1:OTA_AirAvailRS']/@TransactionIdentifier)"

[jcamiel]

Yes ! Exactly, I forget the prefixes (and didn't test it)

We'll improve the xml namespace support so the capture will (probably) be:

POST https://test_api
Content-Type: application/xml; charset=utf-8
file,test.xml;

HTTP/2 200
[Captures]
tr_id: xpath "string(//soap:Envelope/soap:Body/ns1:OTA_AirAvailRS/@TransactionIdentifier)"

(it is not working now)
