  1. POCompare variable in preceding-sibling with current node
    text
    copied!<p>I have the following template:</p> <pre><code>&lt;xsl:template match="footnote"&gt; &lt;xsl:variable name = "string"&gt; &lt;xsl:value-of select="."/&gt; &lt;/xsl:variable&gt; &lt;xsl:variable name = "bool"&gt; &lt;xsl:if test="$string = preceding-sibling::node()/$string"&gt; &lt;xsl:text&gt;false&lt;/xsl:test&gt; &lt;/xsl:if&gt; &lt;/xsl:variable&gt; &lt;xsl:if test="$bool != 'false'"&gt; &lt;!-- DO STUFF --&gt; &lt;/xsl:if&gt; &lt;/xsl:template&gt; </code></pre> <p>I'm trying to check the $string variable of the current node and check it against all previous footnote nodes to see if they have the same $string variable. If it doesn't match up with any of the preceding siblings then it should do stuff, otherwise it should do nothing.</p> <p>With the code I have, the test "$string = preceding-sibling::node()/$string" always evaluates to true, even when no footnote nodes have been created yet.</p> <p>Can anyone help me out? I'm having a hard time creating the expression to compare against the variable in all of the previous siblings.</p> <p><strong>EDIT:</strong> Sample XML:</p> <pre><code>&lt;xml&gt; &lt;footnote&gt;Footnote 1&lt;/footnote&gt; &lt;footnote&gt;Footnote 2&lt;/footnote&gt; &lt;footnote&gt;Footnote 1&lt;/footnote&gt; &lt;footnote&gt;Footnote 1&lt;/footnote&gt; &lt;footnore&gt;Footnote 3&lt;/footenote&gt; &lt;/xml&gt; </code></pre> <p>I'm trying to transform that into:</p> <pre><code>&lt;xml&gt; &lt;footnote&gt;Footnote 1&lt;/footnote&gt; &lt;footnote&gt;Footnote 2&lt;/footnote&gt; &lt;footnote&gt;Footnore 3&lt;/footnore&gt; &lt;/xml </code></pre>
