help with Xpath and Soap message

[talldutchguy]

Hi,

I am trying to parse several details from a SOAP message.

I have looked at many post and i think i need to use xpath.

However, each time i get an error, so i must be formatting my xpath statements incorrect:

InvalidTemplate. Unable to process template language expressions in action 'Compose_2' inputs at line '1' and column '2032': 'The template language function 'xpath' parameters are invalid: the 'xpath' parameter must be a supported, well formed XPath expression. Please see https://aka.ms/logicexpressions#xpath for usage details.

this is the flow:

it is an HTML POST request that revives a SOAP message back.

the result of the HTTP is the following: 

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Header/>
<SOAP-ENV:Body>
<ipgapi:IPGApiActionResponse xmlns:ipgapi="http://ipg-online.com/ipgapi/schemas/ipgapi" xmlns:a1="http://ipg-online.com/ipgapi/schemas/a1" xmlns:v1="http://ipg-online.com/ipgapi/schemas/v1">
<ipgapi:successfully>true</ipgapi:successfully>
<ipgapi:OrderId>A-60e00f5b-SomeID</ipgapi:OrderId>
<ipgapi:TransactionId>84521877SomeTransact</ipgapi:TransactionId>
<ipgapi:Url>https://test.p-online.com/connect/processing?store=SomeStore</ipgapi:Url>
</ipgapi:IPGApiActionResponse>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

for example i am trying to parse the TransactionID and / or the URL.

I have tried several versions, but i keep getting invalid XPATH

xpath(xml(body('Http')), 'string(/SOAP-ENV:Envelope/SOAP-ENV:Body/ipgapi:IPGApiActionResponse/ipgapi:TransactionId)')

xpath(xml(body('Http')), 'string(/*[name()=\"SOAP-ENV:Envelope\"]/*[name()=\"SOAP-ENV:Body\"]\"]/*[name()=\"ipgapi:IPGApiActionResponse\"]\"]/*[name()=\"ipgapi:TransactionId\"])')

testing this in a xpath tester i do get the correct results

any insights would be appreciated - thank you in advance

Hi @talldutchguy 

The issue might be because of the Namespaces in your XML. Can you try out below expression in the Compose action:

xpath(xml(body('Http')), '//*[local-name()="Envelope"]/*[local-name()="Body"]/*[local-name()="IPGApiActionResponse"]/*[local-name()="TransactionId"]/text()')

Hope this Helps!
