(using XSLT 1)
I would like to group numbers by if the following number is current
number + 1 and so on.
Example:
<a>1</a>
<a>3</a>
<a>4</a>
<a>5</a>
<a>7</a>
<a>9</a>
<a>10</a>
<group><a>1</a></group>
<group><a>3 <a>4</a> <a>5</a></group>
<group><a>7</a></group>
<group><a>9</a> <a>10</a></group>
Any insight will be appreciated.
You can use keys as illustrated below.
I hope this helps.
