I have a xml file (I attached the file). I can retrieve related variables in xml file but when it comes to store them with using loop, I got error. I tried to store variable as follows;
docNode = xmlread('2017-03-03.xml');
l = docNode.getElementsByTagName('aSqRoot');
char(l.item(0).getFirstChild.getData); %first aSqRoot value
for i = 0:(l.getLength - 1)
x(i)=char(l.item(i).getFirstChild.getData); % all aSqRoot in almanac file
end
How can I store the below variable?
char(l.item(i).getFirstChild.getData)

sermet - the error message is telling you that you are trying to access an element in an array with an index that is invalid. Indices must be integers and positive (greater than zero). Try changing your code from
for i = 0:(l.getLength - 1)
to
for i = 1:l.getLength
so that we avoid the zero index (unlike other languages like C++ where we would use a zero index).
