I'm looking through the example code and I have a few questions.
- Is it possible to have parameters in the tags? For example:
element_ptr g_elem = root->insert_element("g"); g_elem->add_parameter("stroke_color", "red");
produces:
<g stroke_color = "red"> .. </g>
Is this what append_element() does, or is there another function to do this?
What you call a 'parameter' is actually called an 'attribute', and it gets set like g_elem->set_parameter("stroke_color", "red"); (it can't be "added" since it may only exist once. Thus, you can set and unset it.)
- The operator->() syntax.. It would appear that you did this because all of the elements act as pointers. However, I feel that some of the operations
precisely.
are unclear as to why they should be implemented using the -> syntax
my_elem -> write_to_file("my_file.xml"), for example.
'write_to_file' is a method of 'document', not 'element'. The reason why I expect applications to hold document pointers is that they often get instantiated by a parser (acting as a factory).
- Also, how far does the pointer analogy carry? If I call
++my_elem();
does this go to the next child of my_elem->parent()?
No. an element doesn't have iterator semantics.
I second the call for documentation from Mathias. This nonwithstanding, good work so far!
Thanks ! And yes, I will do my best to write some documentation (beside some API reference that can be readily extracted via synopsis or doxygen). Thanks for the feedback, Stefan -- ...ich hab' noch einen Koffer in Berlin...
