推荐答案

不幸的是，XSLT没有附带padding函数，优点是这样做非常简单，如本博客文章所指出:

Unfortunately XSLT does not comes with the padding function, the good part is that is very simple to do so as pointed by this blog post: http://www.dpawson.co.uk/xsl/sect2/padding.html.

例如，如果您想右填充10个空格字符串，则可以执行以下操作:

For example if you want to right pad a 10 spaces string you can do:

<xsl:value-of 
 select="substring(concat($string, '          '), 1, 10))"/>

如果需要左键盘，则可以按以下方式更改concat参数的顺序:

if you need a left pad you can change the order of the concat parameters as following:

<xsl:value-of 
 select="substring(concat('          ', $string), 1, 10))"/>

请注意，带空格的字符串应包含与填充所需字符数量相同的字符，因此，如果要使用10个填充，则将需要10个空格字符串.

Notice that the string with spaces should contain the same amount of chars as your padding is needing, so if you want a 10 pad, you will need a 10 spaces string.
