xml - 否则需要 xsl:for-each？

问题描述

这是我卡住的 xslt 的最后一部分，有人建议我错过了什么吗？也许 xsl:otherwise 不需要 xsl:for-each 或者我的循环不正确？我已经尝试从 xsl:otherwise 部分中删除“祖先”，但它有效。我已经在 xsl:otherwise 部分尝试了 xsl:variable（命名为 cost），但它也不起作用。

解决方案

xsl:for-each作品中相对于它所设置的上下文节点的表达。
所以只需更改

<xsl:value-of select="productInContracts/ES_CMProductInContract/broadcastRights/ES_CM2BROADCASTRIGHT/broadcastRightGroup/ES_BROADCASTRIGHTGROUP/costDefinitions/ES_CM2CostDefinition/costGroup/ESP_2COSTGROUP/@name"/>

到

<xsl:value-of select="costGroup/ESP_2COSTGROUP/@name"/>

在这两种<Cell ss:Index="2" >...情况下。
现在您应该获得所需的输出。

然而，在上面的例子中，

<xsl:when test="productInContracts/ES_CMProductInContract/episodesInContract">

永远达不到。所以可能没有必要。
