将整数值转换为重复字符 [英] Transform an integer value to a repeated character

问题描述

当我的 XSL 样式表遇到这个节点时:

When my XSL stylesheets encounters this node:

<node attribute="3"/>

...它应该把它转换成这个节点:

...it should transform it into this node:

<node attribute="***"/>

我的模板匹配属性并重新创建它，但我不知道如何将值设置为:字符*"重复的次数与原始属性的值一样多.

My template matches the attribute and recreates it, but I don't know how to set the value to: the character '*' repeated as many times as the value of the original attribute.

<xsl:template match="node/@attribute">
    <xsl:variable name="repeat" select="."/>
    <xsl:attribute name="attribute">
        <!-- What goes here? I think I can do something with $repeat... -->
    </xsl:attribute>
</xsl:template>

谢谢！

推荐答案

一个相当肮脏但实用的方法是调用你期望在 attribute 中看到的最高数字，然后使用

A fairly dirty but pragmatic approach would be to make a call on what's the highest number you ever expect to see in attribute, then use

substring("****...", 1, $repeat)

您在该字符串中的 * 数量与您期望的最大数量一样多.但我希望有更好的东西！

where you have as many *s in that string as that maximum number you expect. But I hope that there's something better!
