Matching values in the XML before output!

<SORRY LAST MESSAGE HAD NO SUBJECT LINE!>

Hi to the forum,

Firstly may I thank all that might be able to assist me with this problem I am currently having, Thanks!

What I am trying to do is get the results that match each common node of <icc-point-number> e.g. when I 
query the XPath icc/icc-phases/icc-points/point-number to output point-number 1, I then want it to match the 
XPath iso-point-details/de-isolation-history/icc-point-history-oid to the point-number e.g. this being the value 
29 where the <icc-point-number> matches on this case 196.

The XML :-
<report-root>
    <icc>
        <icc-phases>
            <icc-points>
                <point-number>1</point-number>
                <icc-point-oid>196</icc-point-oid>
            </icc-points>
            <icc-points>
                <point-number>2</point-number>
                <icc-point-oid>197</icc-point-oid>
            </icc-points>
        </icc-phases>
    </icc>
    <iso-point-details>
        <isolation-history>
            <icc-point-history-oid>15</icc-point-history-oid>
            <icc-point-oid>197</icc-point-oid>
        </isolation-history>
        <isolation-history>
            <icc-point-history-oid>29</icc-point-history-oid>
            <icc-point-oid>196</icc-point-oid>
        </Isolation-history>
    </iso-point-details>
</report-root>

The XSL :-
<xsl:for-each select="icc/icc-phases/icc-points">
<fo:table-cell>
        <fo:block><xsl:value-of select="point-number"/></fo:block> 
</fo:table-cell>
<fo:table-cell>
        <fo:block><xsl:value-of select="../../../iso-point-details/de-isolation-history/icc-point-history-oid"/></fo:block> 
</fo:table-cell>
</xsl:for-each>

Presently the output is 
POINT NUMBER = 1 - ISOLATION HISTORY OID = 15 
POINT NUMBER = 2 - ISOLATION HISTORY OID = 15

Required output
POINT NUMBER = 1 ISOLATION HISTORY OID = 29
POINT NUMBER = 2 ISOLATION HISTORY OID = 15

Presently the XML is generated by castor and I really don't want to touch it! I am sure that XSL can do what I am aiming at (hopefully) :)

Again any help that anyone may be able to assist on the matter is greatly appreciated....

Kind regards,

George Simpson
