Looking at your code though, I probably should have used Adam's
dom.d too; std.xml was weird to say the least.
There's a couple functions in dom.d too that might have
simplified this:
foreach(EnumsTop; Flds.getElementsByTagName("enumeratedValues")){
foreach(Enums; EnumsTop.getElementsByTagName("enumeratedValue")){
foreach(child; Enums.childNodes){
if(child.tagName=="description"){EnumV.description =
child.innerText();}
if(child.tagName=="name" ){EnumV.name =
child.innerText();}
if(child.tagName=="value" ){EnumV.value =
child.innerText();}
}
This pattern is used throughout, and it is pretty nice. Not
saying it is wrong!
But that could prolly be written:
foreach(Enums; Flds.querySelectorAll("enumeratedValues >
enumeratedValue")) {
EnumV.description =
Enum.optionSelector("description").innerText();
EnumV.name = Enum.optionSelector("name").innerText();
EnumV.value = Enum.optionSelector("value").innerText();
}
The various *selector functions do CSS selector syntax.
querySelector/querySelectorAll returns the first/all matching
element, or null if none. requireSelector returns the first
matching, or throws exception if there is none. optionSelector
returns a wrapper object that is never null so you can call its
methods, but they return null if it was.
Meaning you don't have to explicitly check presence, the
.innerText just returns the null string if the element wasn't
there.
The idea of these is to make navigating xml like this a bit more
convenient.
