You can read XmlParser | Unreal Engine Documentation They have included all the necessary functions

Reviving this because I was searching for the same information for a UE5 project and found the XmlParser doc hard to get started with.

Here’s a small sample that’s working in UE5.1 for me (hope it helps/please let me know if I’m doing this wrong):

FString FilePath(TEXT("C:/abc/xyz.xml"));

FXmlFile MyXml(FilePath, EConstructMethod::ConstructFromFile);

if (MyXml.GetRootNode())
{
    const FXmlNode* RootNode = MyXml.GetRootNode();

    const FString MyChildTag("ChildTag");
    const FXmlNode* MyChildNode = RootNode->FindChildNode(MyChildTag);
}

You can continue getting XML nodes/attributes/content using the above functions/other functions of the FXmlFile class and FXmlNode class and then load into a struct/class/etc depending on what you need to do.

Make sure to include all the necessary headers – for the example above:

#include "XmlFile.h"
#include "XmlNode.h"

Lastly, look into IFileManager if you need to work with file paths to the XML file.
