Xport Interface: markup::iterator::operator --

Decrement operator for markup::iterator, and markup::const_iterator.

markup::iterator& markup::iterator::operator --(); iterator pre-increment

markup::iterator markup::iterator::operator --(int); iterator post-increment

markup::const_iterator& markup::const_iterator::operator --() const;  const_iterator pre-increment

markup::const_iterator markup::const_iterator::operator --(int) const;  const_iterator post-increment

Parameters

None

Remarks

Decrement operator for the markup iterator. First variety is the pre decrement operator, and second variety is the post decrement operator.

Complexity

Constant

Example

#include "xhtml_doc.h"
#include <iostream>

int main(int argc, char* argv[])
{
  using namespace Xport;

  // create a root document
  document doc(root_doc);

  // insert a unordered list in the body
  markup::iterator it = doc.body()->insert(element(ul));
  *it << (element(li) << "Item 1");
  *it << (element(li) << "Item 2");
  *it << (element(li) << "Item 3");

  // send the doc to cout
  formatter fmtr(std::cout);
  fmtr << doc;
  std::cout << "\n\n";

  // use the iterator to traverse the unordered list in reverse
  it = it->end();
  --it;
  fmtr << *it;
  --it;
  fmtr << *it;
  --it;
  fmtr << *it;
}
