How to parse and edit XML in TypeScript without converting to JSON - node.js

I need to repair an XML file in TypeScript and I cannot find any info on it, since everyone who posts something like this has different needs. I'd like to be pointed in the right direction here.
I have an XML request as shown below. It is autogenerated by node-soap when given JSON. Using the WSDL, node-soap attempts to fill in the namespace prefixes for each property. The problem is, it gets them wrong a lot.
In this example below, q106 should be replaced with hep3.
<soap:Envelope q15="some-good-url" q106="some-good-url-1" q98-"some-good-url-2>
...
<q98:SalesOrderAuditInfo>
<q15:ConfirmedBy xsi:nil="true"></q15:ConfirmedBy>
<q15:ConfirmedDate>0001-01-01T00:00:00</q15:ConfirmedDate>
<q15:CreatedBy>
<q106:ID>103</q106:ID>
<q106:Value>System, System</q106:Value>
</q15:CreatedBy>
<q15:CreatedDate>2022-10-26T00:43:13.413</q15:CreatedDate>
<q15:SalesOrderType>Standard</q15:SalesOrderType>
</q98:SalesOrderAuditInfo>
I know which namespace prefixes are bad because I have a sample request that was supplied to me. It's just XML. It looks like this:
<soap:Envelope hep="some-good-url" hep1="some-good-url-1" hep2-"some-good-url-2 hep3="some-good-url-3">
...
<hep2:SalesOrderAuditInfo>
<hep:ConfirmedBy xsi:nil="true"></hep:ConfirmedBy>
<hep:ConfirmedBy:ConfirmedDate>0</hep:ConfirmedByConfirmedDate>
<hep:CreatedBy>
<hep3:ID>103</hep3:ID>
<hep3:Value>System, System</hep3:Value>
</hep:CreatedBy>
<hep:CreatedDate>0</hep:CreatedDate>
<hep:SalesOrderType>Standard</hep:SalesOrderType>
</hep2:SalesOrderAuditInfo>
Here is the part that really matters. The Sample Request is the entire possible request body. The supplied request (with incorrect namespaces) is a subset of the sample request. I need to loop through each of the elements in the supplied request, and check to make sure the URL of that element matches the URL of the respective element in the sample request.
So in this example, loop through each element of supplied request. Start with SalesOrderAuditInfo. It's namespace URL is some-good-url-2. If we check the Sample Request, we can see that SalesOrderAuditInfo also corresponds to some-good-url-2.
Continue until we hit the ID tag. This has a namespace set to some-good-url-1. If we check the Same ID (inside of CreatedBy, inside of SalesOrderAuditInfo), we can see the namespace should actually be set to some-good-url-3. So we replace q106 with hep3.
I also need to take all of the namespaces defined in the Sample Request Envelope and move them into the supplied request envelope so that this new hep3 will be defined.
At this point, I need to edit the namespace prefix. In this example, q106:ID would be replaced be the string hep3:ID. Same with all of the closing tags.
Which library can I use to accomplish this in XML? Is anyone familiar with node-soap screwing these namespaces up and know of any fix?
I am using node-soap v0.43

Can't seem to find the issue with the requestID parameter for the request header

I am trying to pull data from a REST API that uses a "similar standard to JSON RPC". The params I am passing look right according to the documentation here and here.
The error I am receiving is ...message:"Header missing request ID".... I am unsure what I am missing that would properly declare the requestID.
I have looked at the documentation provided via the API I am trying to pull data from but it's not very helpful considering it's all in PHP and cURL. I am trying to complete this task using python-requests.
getParams = {'method': 'getCustomers', 'params':{'where':'', 'limit': 2}, 'id': 'getCustomers'}
Result:
{"result":null,"error":{"code":102,"message":"Header missing request ID","data":[]},"id":null}
The return result should contain a list of All Customers and their attributes in JSON format.
Turns out there is nothing wrong with the code I am using. There is an issue with the API I am attempting to call.
In my situation, I was getting the same error back and was required to send a X-Request-ID header. I fixed it by adding the following to my headers:
headers = {
'X-Request-ID': str(uuid.uuid1()) # generate GUID based on host & time
...
Note that (for me) the GUID needed to be of a specific format (e.g. matching the Regex ^[{]?[0-9a-fA-F]{8}-([0-9a-fA-F]{4}-){3}[0-9a-fA-F]{12}[}]?$
taken from https://www.geeksforgeeks.org/how-to-validate-guid-globally-unique-identifier-using-regular-expression/). For example, it still gave the same error if I just sent "test".

SOAP UI how to configure a PUT request body programmatically

I'm configuring some requests programmatically in my test cases, I can set headers, custom properties, teardown scripts, etc. however I can't find how to set a standard json body for my put requests.
Is there any possibility from the restMethod class ?
So far I end up getting the method used :
restService = testRunner.testCase.testSuite.project.getInterfaceAt(0)
resource = restService.getOperationByName(resource_name)
request = resource.getRequestAt(0)
httpMethod = request.getMethod()
if (httpMethod.toString().equals("PUT"))
but then I'm stuck trying to find how to set a standard body for my PUT requests.
I try with the getRequestParts() method but it didn't give me what I expected ...
can anyone help, please
thank you

I’ve managed this. I had a tests of tests where I wanted to squirt the content of interest into the “bare bones” request. Idea being that I can wrap this in a data driven test. Then, for each row in my data spreadsheet I pull in the request body for my test. At first I simply pulled the request from a data source value in my spreadsheet, but this became unmanageable in my spreadsheet.
So, another tactic. In my test data sheet (data source) I stored the file name that contains the payload I want to squirt in.
In the test itself, I put in a groovy step immediately before the the step I want to push the payload into.
The groovy script uses the data source to firstly get the file name containing the payload, I then read the contents of the file.
In the step I want to push the data into, I just use a get from data, e.g. {groovyStep#result}.
If this doesn’t completely make sense, let me know and I’ll update with screenshot when I have access to SoapUi.

How to achieve security level 3 in FIWARE?

I am deploying FIWARE security GEs (i.e., Wilma, AuthzForce, Keyrock) in my computer. Security level 2 (Basic Authorization) is working well, but now I need security level 3 (Advanced Authorization) using XACML.
Long story short, I want a tutorial of implementation security level 3. However, as far as I know, any tutorial or document about security level 3 does not exist.
For now, I create my policy with PAP's API, and change 'custom_policy' option in config.js from 'undefined' to 'policy.js'. And then I create 'policy.js' file into 'PEP/policies', but don't change anything compared with its template file because I don't know what this code does exactly. I think I should make XACML Request form using 'xml' variable. But in my case, PEP gives me the error when I make the XACML Request using 'xml' variable, and return this variable. Here is my error of PEP:
Error: Root - Error in AZF communication <?xml version="1.0" encoding="UTF-8" standalone="yes"?><error xmlns="http://authzforce.github.io/rest-api-model/xmlns/authz/S" xmlns:ns2="http://www.w3.org/2005/Atom" xmlns:ns3="http://authzforce.github.io/core/xmlns/pdp/5.0" xmlns:ns4="http://authzforce.github.io/pap-dao-flat-file/xmlns/properties/3.6"><message>Invalid parameters: cvc-elt.1: Cannot find the declaration of element 'Request'.</message></error>
And here is my 'getPolicy' code (XACML Request) in policy.js. I just made very simple request whether response is permit or not because I'm not sure what I'm doing at that time.:
exports.getPolicy = function (roles, req, app_id) {
var xml = xmlBuilder.create('Request', {
'xmlns': 'urn:oasis:names:tc:xacml:3.0:core:schema:wd-17',
'CombinedDecision': 'false',
'ReturnPolicyIdList': 'false'})
.ele('Attributes', {
'Category': 'urn:oasis:names:tc:xacml:1.0:subject-category:access-subject'});
So, anyone can give me any information about implementation of security level 3?
Upgrade to Wilma 6.2 (bug fixing).
Reuse the code from lib/azf.js which is known to work, and adapt the Request content to your needs. The variable is wrongly called XACMLPolicy there, but don't be mistaken, this is an actual XACML Request. This is using xml2json package to convert the JSON to XML, whereas in your code you seem to use a different one, xmlbuilder maybe? You didn't paste the full code - where does this xmlBuilder variable come from? - so I'm just guessing.
If you are indeed using xmlbuilder package and want to stick with it, I notice that in the example using namespaces, the xmlns attribute is put in a different way:
var xmlBuilder = require('xmlbuilder');
var xml = xmlBuilder.create('Request', { encoding: 'utf-8' })
.att('xmlns', 'urn:oasis:names:tc:xacml:3.0:core:schema:wd-17')
.att('CombinedDecision': 'false')
.att('ReturnPolicyIdList': 'false')
.ele('Attributes', {'Category': 'urn:oasis:names:tc:xacml:1.0:subject-category:access-subject'});
Maybe this makes a difference, I didn't check.
Also feel free to create an issue with your question on Wilma's github to get help from the dev team. (I am not one of them but we've worked together for AuthzForce integration.)
The error you are getting is really
Invalid parameters: cvc-elt.1: Cannot find the declaration of element
'Request'.
This is a simple XML validation issue. You need to make sure that the XACML request you send contains the right namespace declaration.
You'll see there is another question on this topic here.
Can you paste your XACML request so we can tell whether it is valid?

How to display actual value of a property which is using property expansion

I require some help on being able to get around displaying an endpoint from a SOAP Request.
Below I have a piece of code which retrieves an endpoint from a SOAP Request named 'TestAvailability' and outputs it to a file (the code is within a groovy script step).
def endpoint = testRunner.testCase.getTestStepByName('TestStep').get
Now here is the catch, in the file it outputs the endpoint as so:
ENDPOINT: ${#Project#BASE_URL}this_is_the_endpoint
The reason it displays ${#Project#BASE_URL} is because this is a variable set at project level so that the user can select their relevant environment from a drop down menu and that value will be displayed for the variable: ${#Project#BASE_URL}
But I don't want the project variable to be displayed but instead its value like so if ${#Project#BASE_URL} is set to 'testenv'
ENDPOINT: testenv_this_is_the_endpoint
My question is how do I change the code in order to display the endpoint correctly when outputted to a file?
You have a trivial issue. Since it is using property expansion in the endpoint, it request to expand it.
All you need is to change below statement
From:
testResult.append "\n\nENDPOINT: " +endpoint
To:
testResult.append "\n\nENDPOINT: ${context.expand(endpoint)}"

Inserting artificially generated XML into SOAPUI request

I am trying to do the following in SOAPUI:
Read a response and extract a node from it
Insert the node into another request
Generate some xml in a Groovy script and store in a TestCase property
Insert the generated xml from the property as a child node to the node inserted in Step 2.
For 1 and 2: The structure of the response is something like
<A><B>bb</B><C>cc</C><D>dd</D></A>
I extract it via a Property Transfer step using //A to identify the beginning of the node, and passing the node with its children to the request in the next test step. Until this, the node in the request has no content. This works.
For 3 I generate something like
<E>ee</E>
The goal after step 4 is a request structure looking like this:
<A><E>ee</E><B>bb</B><C>cc</C><D>dd</D></A>
A solution using
${#TestCase#new_xml}
to insert the node does not work because there is no way to place the property where the E node should be (as far as I know).
I tried inserting the E node via another Property Transfer test step - the value of the property gets inserted in the request as child to the A node (same way the A node was copied from the response to the next request in Step 2). The result is this:
<A><![CDATA[<E>ee</E>]]<<B>bb</B><C>cc</C><D>dd</D></A>
I would like to know:
How to insert the E node as a child node to the A node while avoiding CDATA (or removing the CDATA subsequently).
Why the xml is passed without CDATA in Step 2 which also uses the SOAPUI Property Transfer Step, but not in Step 4.
Any tips appreciated!
For 1 & 2, you can use just a simple property expansion.
Let say your Response looks like:
<AAA>
<BBB/>
<CCC/>
<BBB/>
<BBB/>
<DDD>
<BBB/>
</DDD>
<CCC/>
</AAA>
And let say you want to transfer the entire node DDD, including the children. In your next request you would use ${<TestStep_name>#Response//*:DDD}. Note the *: means "any namespace", since in a real SOAP Response you will probably have some kind of namespace.
For 3:
// Generate some xml in a Groovy script
def xml = '<AAA><BBB/><CCC/><BBB/><BBB/><DDD><BBB/></DDD><CCC/></AAA>'
// store in a TestCase property
testRunner.testCase.setPropertyValue('my_property', xml)
If you want to get more fancy, you could use one of the many Java XML libraries, some of which are packaged with SoapUI. Here is one possibility.
For 4, you would again use property expansion: ${#TestCase#my_property}
