Question

我有一个XML文件，我需要一个XSL样式表来对它进行分组并获得输出。

<Orders>
    <Order>
        <Client>1234</Client>
        <Amendments>True</Amendments>
        <Address>
            <ID>311</ID>
            <CompanyName>Test</CompanyName>
            <StreetAddress>Sri Lanka</StreetAddress>
        </Address>
        <Line>
            <Client>1234</Client>
            <ItemCode>B100V</ItemCode>
            <Cost>$2.00</Cost>
            <Qty>2</Qty>
            <Group>g2</Group>
        </Line>
        <Line>
            <Client>1234</Client>
            <ItemCode>B102V</ItemCode>
            <Cost>$1.25</Cost>
            <Qty>4</Qty>
            <Group>g3</Group>
        </Line>
        <Line>
            <Client>1234</Client>
            <ItemCode>B140V</ItemCode>
            <Cost>$3.05</Cost>
            <Qty>1</Qty>
            <Group>g1</Group>
        </Line>
        <Line>
            <Client>1234</Client>
            <ItemCode>B113V</ItemCode>
            <Cost>$5.00</Cost>
            <Qty>5</Qty>
            <Group>g2</Group>
        </Line>
    </Order>
</Orders>

我需要按ItemId节点显示每个线路组的Cost和Group，我需要为每个组提供换行符。有人可以帮忙吗？

请注意我的预期输出：

1 of B140V - $3.05  $3.05
                    ------
                    $3.05

2 of B100V - $2.00  $4.00
5 of B113V - $5.00  $25.00
                    ------
                    $29.00

4 of B102V - $1.25  $5.00
                    ------
                    $5.00

</xsl:for-each>
</xsl:variable>
 <total>
            <xsl:variable name="myTotal" select="exslt:node-set($test)"/>
            <xsl:value-of select="concat('$',format-number(sum($myTotal/mine),'#.00'))" />
        </total>

<xsl:text>&#xa;</xsl:text>
          </Line>
    </xsl:template>
<xsl:template name="sumProducts">
        <xsl:param name="mul1"/>
        <xsl:param name="mul2"/> <xsl:text>&#x9;</xsl:text>  
<result><xsl:value-of select='concat("$",format-number(($mul1 * $mul2), "#.00"))'/></result>
</xsl:template>
</xsl:stylesheet>

得到以下结果：

2 of B100V - $2.23	$4.46
5 of B113V - $5.00	$25.00
6 of B113V - $9.00	$54.00
			------
			$83.46
4 of B102V - $1.25	$5.00
10 of B102V - $10.57	$105.70
			------
			$110.70
1 of B140V - $3.05	$3.05
7 of B140V - $7.05	$49.35
			------
			$52.40
