I use 'sum function' to calculate the total quantity, the XML structure is a little complex, I searched online, sum function can be used in XSLT 1.0, but I tried it, it does not work for me, I do not know why? 
我使用'sum函数'来计算总量，XML结构有点复杂，我在网上搜索，sum函数可以在XSLT 1.0中使用，但我试过了，它对我不起作用，我不知道为什么？
my XSLT: 我的XSLT：
<xsl:template match="/">
<html>
<body>
<table border="1">
<tr>
<th>Quantity</th>
</tr>
<xsl:for-each select="warehouses/warehouse">
<tr>
<td><xsl:value-of select="sum(items/item/s_qty)"/></td>
</tr>
</xsl:for-each>
</table>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
my XML : 我的XML：
<warehouses>
<warehouse>
<w_id>22</w_id>
<w_name>Namekagon</w_name>
<address>
<w_city>Indonesia</w_city>
<w_country>Indonesia</w_country>
</address>
<items>
<item>
<i_name>MECLIZINE HYDROCHLORIDE</i_name>
<s_qty>909</s_qty>
</item>
</items>
</warehouse>
<warehouse>
<w_id>21</w_id>
<w_name>kagon</w_name>
<address>
<w_city>Indonesia</w_city>
<w_country>Indonesia</w_country>
</address>
<items>
<item>
<i_name>MECLIZINE HYDROCHLORIDE</i_name>
<s_qty>587</s_qty>
</item>
</items>
</warehouse>
<warehouse>
<w_id>21</w_id>
<w_name>kagon</w_name>
<address>
<w_city>Singapore</w_city>
<w_country>Singapore</w_country>
</address>
<items>
<item>
<i_name>MECLIZINE HYDROCHLORIDE</i_name>
<s_qty>587</s_qty>
</item>
</items>
</warehouse>
the result should be: 1496 结果应该是：1496

if you want sum for all s_qty, you have to change 如果你想要所有s_qty的总和，你必须改变
<xsl:for-each select="warehouses">
<tr>
<td><xsl:value-of select="sum(warehouse/items/item/s_qty)"/></td>
</tr>
</xsl:for-each>
see transformation at https://xsltfiddle.liberty-development.net/bnnZW7 请参阅https://xsltfiddle.liberty-development.net/bnnZW7上的转型
also you can use <xsl:value-of select="sum(//s_qty)"/> 你也可以使用<xsl:value-of select="sum(//s_qty)"/>
