You're not using an input function that skips whitespace (which includes newlines), are you?

no...right now, if there are newlines or whatever, it prints them out .... but i dont want that
but i am skipping any extraneous whitespace
this is the code:
(its not the most effecient, its just a basic program for a web design class to print out the tree structure)
i want it to print it without newlines:
so yea, im trying to get rid of any extraneous whitespace, and check for newlines so i can get rid of it and print on one line
but i am skipping any extraneous whitespace
<img src= ..../> turns into <img src=..../>
this is the code:
(its not the most effecient, its just a basic program for a web design class to print out the tree structure)
#include<iostream>
using namespace std;
int main()
{
char currentChar, peekChar, prevChar;
int tabIndex, tabSize, innerLength, subIndex, numSpaces;
int i;
tabIndex = 0;
tabSize = 4;
innerLength = 0;
while (!cin.eof())
{
currentChar = cin.get();
if (currentChar == '<')
{
peekChar = cin.peek();
if (peekChar == '!')
{
tabIndex--;
}
if (peekChar == '/')
{
subIndex = 1;
}
else
{
tabIndex++;
}
if (peekChar == '\n')
{
cout<<"::::::::FOUND AN END OF LINE CHARACTER::::::::::::::::";
}
for (i=0; i<(tabIndex*tabSize); i++)
{
cout<<" ";
}
while(currentChar != '>')
{
cout<<currentChar;
prevChar = currentChar;
currentChar = cin.get();
if (currentChar == ' ')
{
cout<<currentChar;
while (currentChar == ' ')
{
currentChar = cin.get();
}
}
}
if (prevChar == '/')
{
subIndex = 1;
}
if (subIndex == 1)
{
tabIndex--;
subIndex = 2;
}
cout<<currentChar<<endl;
}
}
return 0;
}i want it to print it without newlines:
<img src="http....." /> is printed as <img src="http...." />
so yea, im trying to get rid of any extraneous whitespace, and check for newlines so i can get rid of it and print on one line

Don't you want the newline check inside the inner while loop? You've checked for a '<' followed immediately by a newline if I'm reading that correctly.
