否则需要 xsl:for-each？答案

【问题标题】：otherwise need xsl:for-each?否则需要 xsl:for-each？
【发布时间】：2021-01-06 06:47:51
【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（命名成本），但它也不起作用。

【问题讨论】：

标签： xml xpath xslt-1.0

【解决方案1】：

xsl:for-each 中的表达式相对于它设置的上下文节点起作用。
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<Cell ss:Index="2" >... 两种情况下。
现在你应该得到想要的输出了。

然而，在上面的例子中，

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

永远不会到达。所以可能没有必要。

【讨论】：

在此答案之后，问题已更新，使其过于宽泛。
谢谢，一切正常。您能否帮助解决“更难的部分：我如何像这样分离 costgrp：”部分？
啊，我明白了，我会把这段代码放在她的新问题中，谢谢
