  1. POXSLT-1.0 can a variable be used to access to other nodes?
    text
    copied!<p>With a simple XML like this</p> <pre><code>&lt;value&gt; &lt;num&gt; &lt;accession&gt;111&lt;/accession&gt; &lt;sequence&gt;AAA&lt;/sequence&gt; &lt;score&gt;4000&lt;/score&gt; &lt;/num&gt; &lt;/value&gt; </code></pre> <p>I want to know if it is possible to access to a particular node from a node previously stored in a variable. The XSLT code is very short and explains better what I want to say</p> <pre><code>&lt;xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"&gt; &lt;xsl:output method="xml" indent="yes" omit-xml-declaration="yes"/&gt; &lt;xsl:template match="/value/num"&gt; &lt;xsl:variable name="node"&gt; &lt;xsl:copy-of select="current()"/&gt; &lt;/xsl:variable&gt; &lt;root&gt; &lt;xsl:copy-of select="$node"/&gt; &lt;/root&gt; &lt;/xsl:template&gt; &lt;/xsl:stylesheet&gt; </code></pre> <p>So I store the node in the variable "node". Then I can print the contents of the node with <code>$node</code>.</p> <p>(EDIT) XML output</p> <pre><code>&lt;root&gt; &lt;num&gt; &lt;accession&gt;111&lt;/accession&gt; &lt;sequence&gt;AAA&lt;/sequence&gt; &lt;score&gt;4000&lt;/score&gt; &lt;/num&gt; &lt;/root&gt; </code></pre> <p>What I want to do is to print the contents of a sub-node, like this</p> <pre><code>&lt;xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"&gt; &lt;xsl:output method="xml" indent="yes" omit-xml-declaration="yes"/&gt; &lt;xsl:template match="/value/num"&gt; &lt;xsl:variable name="node"&gt; &lt;xsl:copy-of select="current()"/&gt; &lt;/xsl:variable&gt; &lt;root&gt; &lt;xsl:copy-of select="$node/accession"/&gt; &lt;/root&gt; &lt;/xsl:template&gt; &lt;/xsl:stylesheet&gt; </code></pre> <p>But it gives an error (Component returned failure code: 0x80600008 [nsIXSLTProcessor.transformToFragment]) (check <a href="http://xsltcake.com/slices/lH3JVa/3" rel="nofollow noreferrer">here</a>)</p> <p>(EDIT) The XML that I would want is</p> <pre><code>&lt;root&gt; &lt;accession&gt;111&lt;/accession&gt; &lt;/root&gt; </code></pre> <p>NOTE: The question is not how can I get this output. The question is how, using a variable as in the XSLT provided, can I get this output.</p> <p>(EDIT:SOLVED) Actually it is possible, but as pointed out in the comments, the value of a variable has to be assigned with the "select" attribute if a node-set is required. So this code was not working since the variable had a tree fragment instead of a node-set stored in it (read more information <a href="https://stackoverflow.com/questions/5353668/how-to-store-node-set-in-a-variable-based-on-choose-when-condition">here</a>)</p> <p>Thanks!</p>
