Groups
Hi,
I have the following code:
<data>
<dataset>
<data1>AAA</data1>
<data2>111</data2>
<data3>###</data3>
<data4>text</data4>
</dataset>
<dataset>
<data1>AAA</data1>
<data2>111</data2>
<data3>###</data3>
<data4>text</data4>
</dataset>
<dataset>
<data1>AAA</data1>
<data2>111</data2>
<data3>@@@</data3>
<data4>text</data4>
</dataset>
</data>
Can anyone explain to me how to group the datasets (to peform a count) where data1, data2 and data3 are unique. So the count here would be 2.
