Filtering XML elements based on attribute value using XSLT

See more:

XML

Please help me to find a way to filter elements of XML document based on value of attributes.

Clearly, for a document like this:

<records>
    <record>
        <Rec1>Guy Levy</Rec1>
        <Rec2 Type="1">72910589</Rec2>
        <Rec3 Type="2">some content</Rec3>
        <Rec4 Type="3">some content</Rec4>
        <Rec5 Type="4">some content</Rec5>
        <Rec6 Type="5">some content</Rec6>
        <Rec7 Type="6">some content</Rec7>
    </record>
    <record>
        <Rec1>Bruno Vang</Rec1>
        <Rec2 Type="1">some content</Rec2>
        <Rec3 Type="2">some content</Rec3>
        <Rec4 Type="3">some content</Rec4>
        <Rec5 Type="4">some content</Rec5>
        <Rec6 Type="5">some content</Rec6>
        <Rec7 Type="6">some content</Rec7>
    </record>
</records>

I want to have elements with , for example, attributes Type="1" and Type="3":

<records>
        <record>
            <Rec1>Guy Levy</Rec1>
            <Rec2 Type="1">72910589</Rec2>
            <Rec4 Type="3">some content</Rec4>
        </record>
        <record>
            <Rec1>Bruno Vang</Rec1>
            <Rec2 Type="1">some content</Rec2>
            <Rec4 Type="3">some content</Rec4>
        </record>
    </records>

Thanks
