使用 Altova Stylevision 的 Autocalc 功能中的 Xpath 表达式将冗长的行分成多行

Question

我有一个 XML 行，其中有一个很长的句子，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!

我需要将句子分成更小的句子，并在 Altova Stylevision 中以多行显示。

我正在使用 Autocalc 动态显示行中的内容。是否有任何 Xpath 表达式可用于根据每行中的字数或字符数将行拆分为多行。以便我可以将行显示为：

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

等等。

Answer 1

您似乎正试图将您的字符串输入分成多个部分（单词/字符串长度）。我为您创建了一个示例，以使其变得容易。请通过并检查它是否可以帮助您：

输入xml

<?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>
