如何防止XSLT中的单词截断

xslt

如何防止XSLT中的单词截断,xslt,Xslt,我在XSLT（1.0）中有一个巨大的字符串，我必须将这个字符串分成一定数量的字符串（这是一个静态数字）和一定长度的字符串（这也是一个静态数字），但我不应该让单词被截断。例如：我有以下字符串这是为了在打印应用程序PDF时测试word cut产品长度为35的String1应为：这是为了测试单词cut 带35的String2应为：在印刷中提供第3条剩余全部：应用程序PDF 还请建议如何在XSLT2.0中执行此操作。这里是一个简单的解决方案，使用str拆分为行模板，从 <xsl:sty

我在XSLT（1.0）中有一个巨大的字符串，我必须将这个字符串分成一定数量的字符串（这是一个静态数字）和一定长度的字符串（这也是一个静态数字），但我不应该让单词被截断。例如：我有以下字符串

这是为了在打印应用程序PDF时测试word cut产品

长度为35的String1应为：这是为了测试单词cut

带35的String2应为：在印刷中提供

第3条剩余全部：应用程序PDF

还请建议如何在XSLT2.0中执行此操作。

这里是一个简单的解决方案，使用
str拆分为行
模板，从
