在XSLT中使用if-else语句和for-each是实现条件判断和循环的常用技巧。 if-else语句用于根据条件执行不同的操作。在XSLT中,可以使用<xsl:choose>元素来实现if-else语句的功能。下面是一个示例: 代码语言:txt 复制 <xsl:choose> <xsl:when test="条件1"> <!-- 条件1成立时执行的操作 --> </xsl:when> <xs...

if (condition1 && condition2) { // 如果 condition1 和 condition2 都为真,则执行该代码块 } else { // 如果 condition1 和 condition2 中任意一个为假,则执行该代码块 } 其中,condition1 和 condition2 是两个待判断的条件,可以是任何返回布尔值的表达式或函数。 嵌套的if-else函数中的AND运算符可以...
Thanks for your help. The goal is to check for every distinct VRPlanID value that we build the tag Group the corresponding MSTP, MSONPC (distinct) if they're not null/empty in the id part of the tag. So, we group after VRPlanID, then get the distinct values from each record from ...
PHP中通过if、elseif、else和switch语句实现条件控制。这一节我们就分析下PHP中两种条件语句的具体实现。 if语句 If语句用法: IF语句有两部分组成:condition(条件)、statement(声明),每个条件分支对应一组这样的组合,其中最后的else比较特殊,它没有条件,编译时......
