Format xml grouping by date??????

[dallasweb]

Hello all,

Here is my xml doc and desired output. I'm pretty new to using xslt and this has really stumped me. So any help is appreciated.

XML:
<VitalSignsComponent>
<patient_info>
<vitals>
<type>bp</type>
<date>04/14/2003</date>
<time>13:15:00</time>
<sys_value>157</sys_value>
<dia_value>99</dia_value>
<mean_value>118</mean_value>
</vitals>
<vitals>
<type>bp</type>
<date>04/14/2003</date>
<time>13:30:00</time>
<sys_value>145</sys_value>
<dia_value>94</dia_value>

</vitals>
<vitals>
