Joints position extraction

Hi, I'm dealing with the output .dae file and want to extract the joints position from the file to plot the skeleton in my project. After I found the "visual_scene", I visit all nodes and get their information of translation and rotation like showing below. So I translate x, y, z based on their parent's position and rotate it by Y, X, Z axis by their degrees respectively. But the skeleton I plot goes to a mess. Is there anything I missed during this process? BTW, the 'inverse_bind_matrix' is the identity matrix. Hope you could help me with it.

```

<translate sid="translate">-0.088257 -0.092568 -0.056613</translate>
<rotate sid="rotateY">0 1 0 -97.791161</rotate>
<rotate sid="rotateX">1 0 0 -1.866507</rotate>
<rotate sid="rotateZ">0 0 1 87.608734</rotate>
<rotate sid="jointOrientY">0 1 0 0.000000</rotate>
<rotate sid="jointOrientX">1 0 0 -0.000000</rotate>
<rotate sid="jointOrientZ">0 0 1 0.000000</rotate>

```

You have to reconstruct the skeleton hierarchy based on the translate, rotation and orientation that you see. I would suggest looking at the COLLADA documentation for details.
