在Altova Stylevision的Autocalc功能中使用Xpath表达式将长行拆分为多行

我有一个XML行，它有一个很长的句子，例如：

    <ROW>4.)Whatever universe a professor believes in must at any rate be a universe that lends itself to lengthy discourse. A universe definable in two sentences is something for which the professorial intellect has no use. No faith in anything of that cheap kind!

以此类推。

您似乎试图将字符串输入分成多个单词/字符串长度。我已经为您创建了一个示例，使其变得简单。请仔细阅读并检查它是否能帮助您：

输入xml

XSLT

输出：

    Whatever universe a professor believes in must at any rate
    be a universe that lends itself to lengthy discourse.

<?xml version="1.0" encoding="UTF-8"?>
<ROW>4.)Whatever universe a professor believes in must at any rate be a universe that lends itself to lengthy discourse. A universe definable in two sentences is something for which the professorial intellect has no use. No faith in anything of that cheap kind!11</ROW>
