Assuming that pWeek represents the node W20200622, how can I get a name at a specific index? For example:

Items[0]/Item/Name

?? I could not see an example. I don't want to just iterate the collection but access a specidic name in the Items list on demand.

Thank you.

This does not work:

UpdateAssignForWeek(5, "Items[0]/Item/Name", &CChristianLifeMinistryEntry::SetTreasures1);
UpdateAssignForWeek(6, "Items[1]/Item/Name", &CChristianLifeMinistryEntry::SetTreasures2);

It returns the same first item on both occasions. The lambda:

auto UpdateAssignForWeek = [this, listMidweekAssign, pWeek, pEntry](int iAssign, std::string strElement, MWBAuto::SetAssignNameFunc fncSetAssignName)
{
	if (listMidweekAssign.at(iAssign))
	{
		auto pElement = tinyxml2::find_element(pWeek, strElement);
		if (pElement == nullptr)
		{
			AfxThrowMemoryException();
		}

		CString strNameToUse;
		strNameToUse = CA2CT(pElement->GetText(), CP_UTF8);
		(pEntry->*fncSetAssignName)(strNameToUse);
	}
};

For now, I have it working using this logic:

int iItemIndex = 0;
for (auto pName : tinyxml2::selection(pWeek, "Items/Item/Name"))
{
	iItemIndex++;

	if (iItemIndex == 3) continue; // Skip

	if (pName != nullptr)
	{
		CString strNameToUse(tinyxml2::text(pName).c_str());

		if (iItemIndex == 1 && listMidweekAssign.at(5))
		{
			pEntry->SetTreasures1(strNameToUse);
		}
		else if (iItemIndex == 2 && listMidweekAssign.at(6))
		{
			pEntry->SetTreasures2(strNameToUse);
		}
		else if (listMidweekAssign.at(9))
		{
			if (iItemIndex == 4 && pEntry->GetNumLivingAssignments() >= 0)
			{
				pEntry->SetLiving1(strNameToUse);
			}
			else if (iItemIndex == 5 && pEntry->GetNumLivingAssignments() >= kLacItemCount2)
			{
				pEntry->SetLiving2(strNameToUse);
			}
			else if (iItemIndex == 6 && pEntry->GetNumLivingAssignments() == kLacItemCount3)
			{
				pEntry->SetLiving2b(strNameToUse);
			}
		}
	}
}

But if there is a simple tweak I can make so that I could just use Items[n]/Item/Name it would be cool. Thanks.
