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!

Thank you so much! it works, this in the final result

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

@yashag2255 - I am trying to accomplish something similar, and I've used your suggestion, but I must be missing something, I can't seem to make it work, the output of the compose step is blank.   Here is a sample of the XML that gets returned from in the API response that is going into the Compose step....I need to be able to use the data under <RESOURCES><AIRCRAFT>.

I've tried this so far...but the compose output is just BLANK.

xpath(xml(body('Operations_-_Aircraft_Info')), '//*[local-name()="Envelope"]/*[local-name()="Body"]/*[local-name()="etaWebServicesResponse"]/*[local-name()="RESOURCES"]/text()')

Sample API XML response data.  

<?xml version='1.0' encoding='UTF-8'?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <SOAP-ENV:Body>
        <ns1:etaWebServicesResponse xmlns:ns1="http://ws.talonsystems.com/Talonws.wsdl" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
            <return xsi:type="xsd:string">
                <RESOURCES>
                    <AIRCRAFT>
                        <AIRCRAFT_ID>XX</AIRCRAFT_ID>
                        <AIRCRAFT>XXXXXX</AIRCRAFT>
                        <SITE_ID/>
                        <SITE/>
                        <DESCRIPTION>XXXXXX</DESCRIPTION>
                        <RESOURCE_TYPE>XXXXX</RESOURCE_TYPE>
                        <COLOR>XXXXXX</COLOR>
                        <AIRCRAFT_CLASS>XXXXX</AIRCRAFT_CLASS>
                        .....
                        .....
                   </AIRCRAFT>
                </RESOURCES>
            </return>
        </ns1:etaWebServicesResponse>
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

Hi folks, 

I have been struggling with a similar situation.

I have following SOAP response body to parse using xpath in my flow. This response is received by in flow after calling the custom connector to read data from a legacy NAV. I need the value in the XML tag.

<Soap:Envelope xmlns:Soap="http://schemas.xmlsoap.org/soap/envelope/"><Soap:Body><GetRecIdFromKey_Result xmlns="urn:microsoft-dynamics-schemas/page/crm_contact_stg_ws"><GetRecIdFromKey_Result>CRM Contact Stg: 4801</GetRecIdFromKey_Result></GetRecIdFromKey_Result></Soap:Body></Soap:Envelope>

I have tried a number of xpath expressions to get the value from this tag, but I have hit the wall. I really wonder if somebody shares similar experience as I just do. I used online xpath tool as here https://www.freeformatter.com/xpath-tester.html, but many expressions that work here, do not give any results when used as xpath expression in flow. Have you observed the same ? as a standard, any xpath expression (irrespective of which tool it is used in), should give same result ? Or correct me if i am wrongly assuming this.

Anyway, can somebody get me the value of the innermost tag <GetRecIdFromKey_Result>  ?

Thanks
