I have the following content structure:

Parent
- Child 1
- Child 2
- ...
- Child 7

On the page I am displaying any one of the children nodes as the main video. Then I would like to display 5 other videos under the main video the problem I am having is if the child node (main video) is in the next 5 videos when looping it only displays 4. Here is my XSLT and sorry for the poor explanation.

<xsl:for-each select="umbraco.library:GetXmlNodeById($source)/node [string(data [@alias='umbracoNaviHide']) != '1']">
    <xsl:sort select="@createDate" data-type="text" order="descending" />
    <xsl:if test="$currentPage/@id != @id">    
        <xsl:if test="position() &lt;= $numberToDisplay">
            <xsl:value-of select="$numberDisplayed + 1" />
        <li class="left">
            <a href="{umbraco.library:NiceUrl(@id)}">
                <img src="/umbraco/imageGen.ashx?image={data [@alias = 'pageThumb']}&amp;width=90&amp;height=70" />
                </a>
                <h5>
                    <a href="{umbraco.library:NiceUrl(@id)}">
                        <xsl:value-of select="data [@alias = 'pageTitle']" />
                    </a>
                </h5>
        </li>
        </xsl:if>
    </xsl:if>
</xsl:for-each>

The source is actually

<xsl:for-each select="umbraco.library:GetXmlNodeById($source)/node [string(data [@alias='umbracoNaviHide']) != '1']">
    <xsl:sort select="@createDate" data-type="text" order="descending" />
    <xsl:if test="$currentPage/@id != @id">    
        <xsl:if test="position() &lt;= $numberToDisplay">
        <li class="left">
            <a href="{umbraco.library:NiceUrl(@id)}">
                <img src="/umbraco/imageGen.ashx?image={data [@alias = 'pageThumb']}&amp;width=90&amp;height=70" />
                </a>
                <h5>
                    <a href="{umbraco.library:NiceUrl(@id)}">
                        <xsl:value-of select="data [@alias = 'pageTitle']" />
                    </a>
                </h5>
        </li>
        </xsl:if>
    </xsl:if>
</xsl:for-each>

The bold line below was removed, tried auto inc method but failed.

<xsl:for-each select="umbraco.library:GetXmlNodeById($source)/node [string(data [@alias='umbracoNaviHide']) != '1']">
    <xsl:sort select="@createDate" data-type="text" order="descending" />
    <xsl:if test="$currentPage/@id != @id">    
        <xsl:if test="position() &lt;= $numberToDisplay">
            <xsl:value-of select="$numberDisplayed + 1" />
        <li class="left">
            <a href="{umbraco.library:NiceUrl(@id)}">
                <img src="/umbraco/imageGen.ashx?image={data [@alias = 'pageThumb']}&amp;width=90&amp;height=70" />
                </a>
                <h5>
                    <a href="{umbraco.library:NiceUrl(@id)}">
                        <xsl:value-of select="data [@alias = 'pageTitle']" />
                    </a>
                </h5>
        </li>
        </xsl:if>
    </xsl:if>
</xsl:for-each>

Well to do it really easily, remove the currentPage node from the nodeset by changing your for-each

<xsl:for-each select="umbraco.library:GetXmlNodeById($source)/node [string(data [@alias='umbracoNaviHide']) != '1']">

to use a predicate [the condition inside square bracket]

<xsl:for-each select="umbraco.library:GetXmlNodeById($source)/node [@id!=$currentPage/@id][string(data [@alias='umbracoNaviHide']) != '1']">
