bool UHermesFunctionLibrary::isFileExist(const FString& Path)
{
	return FPlatformFileManager::Get().GetPlatformFile().FileExists(*Path);
}
 
FString UHermesFunctionLibrary::ReadXmlFile(const FString& Path, bool& isSuccess)

		return FString("");
	}
	TSharedPtr<FXmlFile> XmlFile = MakeShareable(new FXmlFile(Path));
	if(!XmlFile->IsValid()){
		isSuccess = false;
		return FString("");
	}
	FString Content;
	FXmlNode* RootNode = XmlFile->GetRootNode();
	for(FXmlNode* ChildNode : RootNode->GetChildrenNodes())
	{
		FString strValue = ChildNode->GetAttribute("category");
		for(FXmlNode* SubChildNode : ChildNode->GetChildrenNodes())

FString UHermesFunctionLibrary::ReadXmlFile(const FString& Path, const FString& Tag, bool& isSuccess)
{
	TSharedPtr<FXmlFile> XmlFile = MakeShareable(new FXmlFile(Path));
	if(!XmlFile->IsValid() || !isFileExist(Path)){
		isSuccess = false;
		return FString("");
	}
	FXmlNode* RootNode = XmlFile->GetRootNode();
	for(FXmlNode* ChildNode : RootNode->GetChildrenNodes())
	{
		if(ChildNode->GetTag() == Tag)	return ChildNode->GetContent();
	}
 
	return FString("");
}

这里如果要GetTag()则得改成 == title

FString UHermesFunctionLibrary::ReadXmlFile(const FString& Path, const FString& Tag, bool& isSuccess)//暂时做两层用于XML读取，以后升级
{
	TSharedPtr<FXmlFile> XmlFile = MakeShareable(new FXmlFile(Path));
	if(!XmlFile->IsValid() || !isFileExist(Path)){
		isSuccess = false;
		return FString("");
	}
	FXmlNode* RootNode = XmlFile->GetRootNode();
	for(FXmlNode* ChildNode : RootNode->GetChildrenNodes())
	{
		if (ChildNode->GetAttribute("category") == "COOKING")	return ChildNode->GetContent();
		//if(ChildNode->GetTag() == Tag)	return ChildNode->GetContent();
	}
 
	return FString("");
}
