<h1>saxon:while</h1>
<p>The <code>saxon:while</code> element is used to iterate while some condition is true.</p>
<p>The condition is given as a boolean expression in the mandatory test attribute. Because
this expression must change its value if the loop is to terminate, the condition will generally
reference a variable that is updated somewhere in the loop using an <code>saxon:assign</code> element.
Alternatively, it may test a condition that is changed by means of a call on an extension function
that has side-effects. </p>
<p>Example:</p>
<div class="codeblock"
style="border: solid thin; background-color: #B1CCC7; padding: 2px">
<pre>
<code>
<xsl:variable name="i" select="0" saxon:assignable="yes"/>
<xsl:template name="loop">
<saxon:while test="$i &lt; 10">
The value of i is <xsl:value-of select="$i"/>
<saxon:assign name="i" select="$i+1"/>
</saxon:while>
</xsl:template>
</code>
</pre>
</div>
<table width="100%">
