Thank you for your answer. But, the Cases function permit to select all the XMLElements with the desired tag but the hierarchical structure (or tree) of the XMLElements is lost.
Perfectly clear. Thank you
I try this code to delete all the attributes of my XMLElements XMLtest = Block[{XMLElement}, XMLElement[tag_, _, content_] := XMLElement[tag, {}, content]; XMLtest] but it doesn't work, I receive this error message ...
I simply my last question. Thank you in advance for your help My question was : **May you help me to modify this code in order I can add several conditions on the XMLElements that I want to keep in my XMLObjects. ? I need to keep now too types of...
Hello, I would like to better understand the block function. First, is it a recursive function ? I have read the help but I didn't well understand the operation of this function. Here a an example where a Block function is used and that I...
Thank you You perfectly answer to my question.
Hello, I have a matrix M[3,3]. After a solve procedure, I obtained these results. {{M[1, 2] -> Cos[?[t]], M[1, 3] -> 0, M[2, 3] -> 0, Cos[?[t]] -> M[3, 1], M[3, 2] -> 0, M[3, 3] -> 1, M[2, 1] -> -Cos[?[t]] Sin[?[t]], M[2, 2] -> Sin[?[t]],...
Here my code, to help for troubleshouting Equation Psi eq? = (A*cos[?[t]]^2 - C*cos[?[t]]^2 + C)*[???][t] + (-2*A*sin[?[t]]*cos[?[t]] + 2*C*sin[?[t]]*cos[?[t]])* Derivative[?][t]* Derivative[?][t] + ...
OK. Thank you. But I would like to reproduce exactly the cells (for Mathematica inputs) I have in Mathematica.
Hello, Thank you for your help. First, concerning the substraction of two equations, I found on the net on more simple way (to my point of view) : Inner[Subtract, eq\[Psi]Ae, eq\[Psi]E, Equal]; Secondly, I have still a little...
