Find a way to easily reach the internal values of the rendered tree

[G-E-N-E]

I'm not sure if this is a bug or intended behavior but the height of a box is 'auto' after rendering unlike the width of the box which appears to be being calculated based on the content.

How can I get the calculated height of the element id=header from the rendered document, i.e.
doc = HTML(string=html_below).render(stylesheet=[CSS(css_below)])?

It seems like the width of the elements is calculated but the height remains set to 'auto'.
I'd like to resolve this to a unit so unfixed elements (not shown) can be positions relative to the dynamic height.

HTML

<div id="header">
  <div id="header-right">
    <div>Row 1, Column 2</div>
    <div>Row 2, Column 2</div>
  </div>

  <div>
    <div>Row 1, Column 1</div>
    <div>Row 2, Column 1</div>
  </div>
</div>

CSS

#header {
  position: fixed;
  top: 0;
  left: 0;
  right: 0;
}

#header-right {
  float: right;
  text-align: right;
}

There's no "official" and reliable way to get the boxes and their attributes. But with the current version, you can try to get what you want:

>>> doc.pages[0]._page_box.children[0].children[0].children[0]
<Placeholder <BlockBox div None>>
>>> doc.pages[0]._page_box.children[0].children[0].children[0].style['position']
'fixed'
>>> doc.pages[0]._page_box.children[0].children[0].children[0].height
37.28125

AFAIK, there's currently no easy way to automatically get what you want (for example, get the blocks corresponding to your tags using their id), but it may be possible to override some classes and functions if you really need it.

This is the same conclusion I've come too.
I'm in the progress of defining some access functions around id's and element types; I'll post what I come up with in case anyone is interested.

Cool!

I think that 4365b19 gives a nice way to enable post-processing operations. Feel free to reopen if needed!
