Worksheet XML
See §3.13.3 for the full XML. Here is the snippet expressing the hyperlink information, whose collection appears immediately after the <sheetData>
collection in this example.
<hyperlinks> <hyperlink ref="B4" r:id="rId1"/> </hyperlinks>
The hyperlink XML indicates that cell B4
of this sheet has a hyperlink, whose target can be found by following the relationship whose @Id="rId1"
from the current sheet. The 'friendly' name of the hyperlink is stored in the cell definition.
