How to create templated XML document using Mysql as datasource

[Shoaib]

Describe the issue/error/question

Use Case To generate Sales Orders in XML file with a predefined xml template using mysql as data source
We are using a accounting software Tally which supports xml import of data using the templated xml file. Our requirement is to connect the sales crm (Vtiger self hosted open source) system to N8N (using mysql) to generate the XML file according to the xml template (im using set node to feed the template) which will give the sales order xml document for each order ID
Problem:
For single line items the workflow seems to work, but in case where more than one line items are involved (array of products) the workflow doesn’t work. i tried using item list node to combine all items as one. but it didn’t work.

What is the error message (if any)?

Please share the workflow

Share the output returned by the last node

Information on your n8n setup

• **n8n version:**0.204.0
• Database you’re using (default: SQLite):
• Running n8n with the execution process [own(default), main]:
• Running n8n via [Docker, npm, n8n.cloud, desktop app]: npm

Hi @Shoaib, welcome to the community

Perhaps you can share some example data you’d like to convert into an XML document? It seems the Set nodes from your workflow already use some static data, but I guess that’s not what’s coming from MySQL?

I’ve also provided an example workflow recently creating an XML feed and consisting of multiple items which you might find helpful when getting started:

Webflow collection items to XML Feed

Hi @blauwe, you can definitely generate XML data structures using n8n. Here’s a basic example of serving an XML feed through n8n: For each request this workflow receives it will fetch data from an external source offering an API (this would be Webflow in your example), will apply some filtering and formatting logic on it’s own and finally use the Respond to Webhook node to return a response (in this case the upcoming departures from Berlin’s central train station): [im…

Hello @MutedJam,

this is the template / static data using which i want to generate an xml document. The template in already in xml and the end result should consist of the dynamic value in the template, for getting the dynamic data im using mysql.

In this ive used multiple left joins from various tables (customers, products, orders, Organization) to get the data

the xml template here is showing some weird result on pasting it here.

hello @jan can you help me out on this?

[MutedJam]

If your XML file needs to follow a specific structure which you can’t get to work with the XML node itself you can still build the structure manually through the Code node. Check out Create an RSS feed based on a website's content | n8n workflow template for an example (this older example still uses Function/Function Item nodes, but the basic idea would work using the Code node as well).
