How to convert a string to XML using the javascipt model of Apigee

Google Cloud Apigee

I am converting an XML to JSON using Javascript. The XML comes in as a string and I am not able to convert it into an XML object. Can anyone guide me in this regard.

As of now I have tried

var parser=new DOMParser();

xmlDoc=parser.parseFromString(xml,“text/xml”);

It throws an error indicating DOMParser is undefined. The above code is only for browsers, can you help in the execution of Apigee envt?

Dear @dj1 , Is your API publicly accessible ? Ideally if your backend API sets response content type to application/xml then out of the box XML to JSON should work for you. Can you post the XML you are trying to convert ?

you are right, DOMParser is not available in the Apigee env, basically there is no DOM here,

If you want to convert your XML to JSON, then i would strongly recommend you to use XMLToJson policy and then manipulate the json in your js policy

If you still need to parse XML - java is much easier option

If you still need to parse XML in js - you will have to rely on other js libs, maybe libxmljs or xmlbuilder and browserify it [i have not used them in apigee before], so you could include them in your js

Hi dj1,

I think by now you already know the solution but just for the sake of sharing knowledge I am posting this. I faced the same issue yesterday and this is how I resolved it:

 <AssignMessage async="false" continueOnError="false" enabled="true" name="AM-StrToXML">
    <DisplayName>AM-StrToXML</DisplayName>      
    <Properties/>      
 	<Set> 
	    <Headers>
            	<Header name="Content-Type">text/xml; charset=utf-8</Header>
            </Headers>
            <Verb>POST</Verb>
            <Payload contentType="text/xml">{xmlStr}</Payload>
    </Set>
    <IgnoreUnresolvedVariables>true</IgnoreUnresolvedVariables>
    <AssignTo createNew="false" transport="http" type="response"/>
</AssignMessage>

The target was sending me the encrypted xml data which I have to convert to XML then to JSON and then send it back to the API caller.

I think it is self explanatory, but anyone, please feel free to ask in case of any confusion.

Thanks,

ummmm, ya,

You have added a new question, as a response! to a post from literally 7 years ago, and your question has no relation to the 7-year old question. Don’t do that.

Ask a new question, if you have a new question.
