计算子节点

Question

我有低于有效负载，我必须在<Document>下计算子元素的数量。 例如：

<Document>
  <Class>D</Class>`enter code here`
  <ClassDescription>Drawings</ClassDescription>
  <ClientDocumentNumber>12345</ClientDocumentNumber>
<Document>

计数为3。

有效负载如下。检查此代码。

Answer 1

<xsl:template match="Document">
  <xsl:value-of select="count(*)"/>
</xsl:template>

是匹配Document元素并计算子元素的模板。
