implementing XML Namespaces in Angular XML HTTP Requests - Unexpected Data Format
I'm experimenting with I'm collaborating on a project where I tried several approaches but none seem to work. I've been struggling with this for a few days now and could really use some help... I'm working with a question when making XML HTTP requests in my Angular (version 12) application. The backend service returns an XML response that includes namespaces, but when I try to parse it using the Angular HttpClient, I'm losing the namespace information, and as a result, the data is not parsed correctly. Here's an example of the XML response I'm getting: ```xml <ns:response xmlns:ns="http://example.com/ns"> <ns:data> <ns:item id="1">Item One</ns:item> <ns:item id="2">Item Two</ns:item> </ns:data> </ns:response> ``` In my service, I'm using the following method to make the HTTP request: ```typescript getData(): Observable<any> { return this.http.get('http://example.com/api/data', { responseType: 'text' }).pipe( map(response => this.parseXML(response)) ); } ``` The `parseXML` function looks like this: ```typescript private parseXML(response: string): any { const parser = new DOMParser(); const xmlDoc = parser.parseFromString(response, 'text/xml'); const items = xmlDoc.getElementsByTagName('item'); return Array.from(items).map(item => ({ id: item.getAttribute('id'), name: item.textContent })); } ``` When I run this code, I get an empty array because `getElementsByTagName('item')` does not find any elements. I suspect it's due to the namespace in the XML. I've tried switching to `getElementsByTagNameNS` but that didn't work either: ```typescript const items = xmlDoc.getElementsByTagNameNS('http://example.com/ns', 'item'); ``` However, I still get an empty NodeList. I also verified that the XML response is valid by logging it to the console. What am I missing here? Is there a proper way to handle XML namespaces when working with Angular's HttpClient? I really need to retrieve those items and their attributes correctly. What's the best practice here? I'm working on a web app that needs to handle this. Thanks for taking the time to read this! I recently upgraded to Typescript 3.9.
