问题描述
我有两个 xml.有一个金额字段，可以包含 54.2,54.23,54.234,54.234567 之类的值.
I have two xmls.There is a amount field which can contains values like 54.2,54.23,54.234,54.234567.
有人请告诉我如何确保输出 xml 中至少出现两位小数.目前 54.2 被转换为 54,2 ，但我希望它是 54,20
Would someone please tell me how can I make sure that atleast two decimal places will appear in the output xml.Currently 54.2 gets converted to 54,2 , but I want it to be 54,20
推荐答案
您可以使用 format-number() 函数将数字转换为给定格式的字符串.如果使用这个#.00##########"格式字符串，至少会出现两位小数.
You can use the format-number() function to convert a number into a string in a given format. At least two decimal places will be appeared if you use this "#.00##########" format string.
如果您有一个 xml 文件，其中可以包含 54.2,54.23,54.234,54.234567 之类的值:
If you have an xml file which can contains values like 54.2,54.23,54.234,54.234567:
<?xml version="1.0" encoding="ISO-8859-1"?>
<catalog>
<price>54.2</price>
<price>54.23</price>
<price>54.234</price>
<price>54.234567</price>
</catalog>
您可以使用这样的 xslt 转换数字以获得至少两位小数
You can convert the numbers with an xslt like this to get at least two decimal places
<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<html>
<body>
<xsl:for-each select="/catalog/price">
<xsl:value-of select='format-number(., "#.00##########")'/><br />
</xsl:for-each>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
然后输出:
54.20
54.23
54.234
54.234567
