固定长度的填充值 - xslt [英] Pad Value with fix length - xslt

问题描述

我有这个简单的 xslt 代码:

I have this simple xslt code:

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
   <xsl:output method="text" indent="yes"/>
   <xsl:template match="/racine/Requete">
        <xsl:for-each select="Row">
            <xsl:value-of select="Col[@name = 'Service Point']/." />
            <xsl:text>ME02</xsl:text>
            <xsl:value-of select="Col[@name = 'Meter Number']/." />
            <xsl:value-of select="Col[@name = 'Date']/." />
            <xsl:value-of select="translate(Col[@name = 'Import Active kWh']/.,',','.')" />
            <xsl:text>30000000000000000000</xsl:text>
            <xsl:text>&#13;</xsl:text>
        </xsl:for-each>
    </xsl:template>
</xsl:stylesheet>

Meter Number 参数最多可以有 10 个字母数字.因此，例如，如果值是 232345，我想显示(用空格填充):'232345'.我对 Import Active kWh 有同样的情况，这是一个数字字段修复 12 类型的数字，但如果值为 56884，我想显示(以 0 开头)'000000056884'.

The Meter Number parameter can have max 10 alphanumeric. so if for example the value is 232345, I want to display (pad with spaces):' 232345'. I have the same case for Import Active kWh, this is a numeric field fix 12 type numeric, but if the value is 56884, I want to display (pad with 0 at the begining) '000000056884'.

感谢您一如既往的有用帮助！

推荐答案

对于数字字段，您可以简单地使用 format-number() 函数，例如:

For the numeric field you can simply use the format-number() function, e.g.:

<xsl:value-of select="format-number($numeric-field, '000000000000')"/>

对于字母数字字段，请尝试:

For the alpha-numeric field, try:

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

如果您需要多次执行此操作，请考虑将其重新编写为函数.

If you need to do it more than once, consider re-writing this as a function.

注意:这个位置步骤 /. 没有任何作用.

Note: this location step /. doesn't do anything.
