XSL中用count()來取得xml中某種節點的個數
list.xml
<?xml version="1.0"?>
<list>
  <application>
      <id>1</id>
    <state>1</state>
    <type>111</type>
    <title>title</title>
    <applior>applior</applior>
    <PRogress>
      <node>
        <state>pass</state>
        <censor>admin</censor>
      </node>
      <node>
        <state>failure</state>
        <censor>kk</censor>
      </node>
      <node>
        <state>detemind</state>
        <censor>dq</censor>
      </node>
    </progress>
    <applytime>2006-9-06</applytime>
    <deadline>
      <state>delay/ontime</state>
      <time>2006-9-12</time>
    </deadline>
  </application>
</list>
要取得<node>節點的個數可以用的方法是
<xsl:value-of disable-output-escaping="yes" select="count(//node)"/>
路徑以雙斜線 // 開頭, 則表示選擇文檔中所有滿足雙斜線//之后規則的元素(無論層級關系)
