c# - Extremely large XML tree manipulation -

-

i know question might asked somewhere around sof. having search sof, find no matched solution.

i have mission create & maintain/populate extremely large xml tree (approx 2gb on disk). according requirements, have to:

  1. apply lots of transformation logic xml tree's nodes
  2. create new tree, add transformed nodes it, save new tree file.

the first thing in mind when started work on is: don't have enough memory hold file & if have enough memory, performance serious problem if whole tree loaded memory.

with in mind, i'd used stream xml fragments technique read data original file w/o loading memory. create new tree, stuck. msdn seems not have doc deal problem. idea?

thanks in advance.

i'm trying plot frequency characteristic equation using ezplot, matlab gives following warning, "contour not rendered non-finite zdata". have used command plot frequency equations warning , plot display empty , not change axis range well. can please help. appreciated. here's code i'm using. % transfer matrix case-i, thin rotor clear all; clc; ei = 1626; l = 0.15; m = 0.44108; = 2.178*10^-4; i_p = 2.205*10^-5; itr = 0.24; i_pr = 0.479; syms p n; f = [1 l*1i l^2/(2*ei)*1i l^3/(6*ei); 0 1 l/ei -l^2/(2*ei)*1i; 0 0 1 -l*1i; 0 0 0 l]; p = [ 1 0 0 0; 0 1 0 0; 0 -it*p^2+i_p*n*p 1 0; -m*p^2 0 0 1]; p_r = [1 0 0 0; 0 1 0 0; 0 -itr*p^2+i_pr*n*p 1 0; -m*p^2 0 0 1]; = f*p*f*p*f*p*f; b = p_r*f*p*f*p*f; r = a(1,2)/a(1,4); a12_p = 0; a22_p = a(2,2)-r*a(2,4); a32_p = a(3,2)-r*a(3,4); a42_p = a(4,2)-r*a(4,4); ap(2,2) = a22_p; ap(3,2) = a32_p; ap(4,2) = a42_p; ap(4,4) = 1; c = b*ap; m = [c(3,2) c(3,4); c(4,2) c(4,...
