Select node based on sibling's value

Question

I need XPath syntax (for use in simplexml) for searching the contents of the LayoutPosNo element that matches exactly, say, the number 1001 and returning the text in the sibling Descrip element. The LayoutPosNo's are all unique, so I only need the first match.

Here is the structure of the XML:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<data-set xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <record>
        <LayoutPosNo>10</LayoutPosNo>
        <Descrip>This is the red room</Descrip>
    </record>
    <record>
        <LayoutPosNo>993</LayoutPosNo>
        <Descrip>This is the yellow room</Descrip>
    </record>
    <record>
        <LayoutPosNo>1001</LayoutPosNo>
        <Descrip>This is the purple room</Descrip>
    </record>
</data-set>

/data-set/record[LayoutPosNo = 1001]/Descrip/text()

will select

This is the purple room

as requested.
