如何根据条件递增计数器,并使用该计数器测试另一个条件并呈现某些语句? 这是我的输入XML-
<order>
<orderId>Order1</orderId>
<OrderObject>
<OrderType>30</OrderType>
<ObjectID>obj1</ObjectID>
</OrderObject>
<OrderObject>
<OrderType>30</OrderType>
<ObjectID>obj2</ObjectID>
</OrderObject>
<OrderObject>
<OrderType>40</OrderType>
<ObjectID>obj3</ObjectID>
</OrderObject>
</order>
这是我正在尝试的XSLT-
<xsl:variable name="counter" select="'1'"/>
<xsl:variable name="length" select="'5'"/>
<xsl:for-each select="order/OrderObject">
<xsl:choose>
<xsl:when test="OrderType='30">
{
ObjectId : <xsl:value-of select="ObjectID"/>
}
counter = $counter+1;
<xsl:choose>
<xsl:when test="$counter < $length">
<xsl:text>;</xsl:text>
</xsl:when>
</xsl:choose>
</xsl:when>
</xsl:choose>
</xsl:for-each>
预期输出-
{
"ObjectId": "obj1"
};
{
"ObjectId": "obj2"
}

只是过程,例如<xsl:for-each select="order/OrderObject[OrderType = 30]">
,然后在其中检查position() < 5
。
另一种方法不是在最后一项后缀;
,而是在最后一项后加上前缀:
<xsl:for-each select="order/OrderObject[OrderType = 30]">
<xsl:if test="position() > 1">;</xsl:if>
...
</xsl:for-each>
