Displaying Date as DD-MM-YYYY within XSLT/XML

xmldatedatetimexsltxsd

提问by magi4000

Been trying to format the text to display as DD-MM-YYYY when pulled from XML to XSLT 1.0, since I know it has to be laid out as YYYY-MM-DD within XSD/XML when using xs:date which what I have used.

当从 XML 拉到 XSLT 1.0 时,一直试图格式化文本以显示为 DD-MM-YYYY,因为我知道在使用 xs:date 时,它​​必须在 XSD/XML 中布局为 YYYY-MM-DD用过的。

Here is the code I am working working on, Any advice on how I should display this?

这是我正在处理的代码,有关如何显示此代码的任何建议?

Another simple solution for producing dates in dd/mm/yyyy form

以 dd/mm/yyyy 形式生成日期的另一种简单解决方案

<xsl:value-of select="
  concat(substring(@date, 9, 2), 
         '/', 
         substring(@date, 6, 2),
         '/', 
         substring(@date, 1, 4))"/>

I would use different solutions from those provided by @Stormtroopr for both 1.0 and 2.0.

我将使用与@Stormtroopr 为 1.0 和 2.0 提供的解决方案不同的解决方案。

In 2.0 use

在 2.0 中使用

format-date(xs:date($date), '[D01]-[M01]-[Y0001]')

In 1.0 use

在 1.0 中使用

concat(substring(., 9, 2), 
         '-', 
         substring(., 6, 2), 
         '-', 
         substring(., 1, 4))

For future reference, please tell us which version of XSLT you are using. Both 1.0 and 2.0 are in common use, and the solutions are often different.

为了将来参考,请告诉我们您使用的是哪个版本的 XSLT。1.0 和 2.0 都是通用的,解决方法也经常不同。

I am using it for SharePoint and I solved it like this

我将它用于 SharePoint 并像这样解决了它

<xsl:value-of select=" ddwrt:FormatDate(/dsQueryResponse/Rows/Row/@Date,3,1)"/>

In XSLT 2.0 you can use tokenize to split the string and then just using xsl:for-eachand xsl:sortto reverse it. (I don't have an XSLT2.0 engine right now, but this is pretty close to what you'll need).

在 XSLT 2.0 中,您可以使用 tokenize 来拆分字符串,然后只使用xsl:for-eachxsl:sort反转它。(我现在没有 XSLT2.0 引擎,但这与您需要的非常接近)。

<xsl:for-each select="tokenize(@date,'-'">
    <xsl:sort select="position()" data-type="number" order="descending"/>
    <xsl:value-of select="."/>
</xsl:for-each>

In XSLT 1.0, you do it using... recursion!

在 XSLT 1.0 中,您使用...递归!

Here is the crux of it, this takes a date, and then searches for the string before and after the first hyphen (-). Normally, you'd have the substring-beforecome after the processing of the subtring-afterto preserve the order, but here we switch them to ultimately reverse the ouput.

这是它的关键,这需要一个日期,然后搜索第一个连字符 ( -)前后的字符串。通常,您会substring-before在处理 之后使用comesubtring-after来保留顺序,但在这里我们切换它们以最终反转输出。

<xsl:template name="reverse-date">
    <xsl:param name="text" select="."/>
    <xsl:choose>
        <xsl:when test="contains($text, '-')">
            <xsl:call-template name="reverse-date">
                <xsl:with-param name="text" select="substring-after($text, '-')"/>
            </xsl:call-template>
            <xsl:text>-</xsl:text>
            <xsl:value-of select="substring-before($text, '-')" />
        </xsl:when>
        <xsl:otherwise>
           <xsl:value-of select="$text"/>
        </xsl:otherwise>
    </xsl:choose>
</xsl:template>

Below is the complete template that will reverse the date for you based on your above XML document.

下面是完整的模板,它将根据您的上述 XML 文档为您反转日期。

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:template match="/">
  <xsl:apply-templates select="//event"/>
</xsl:template>

<xsl:template match="event">
  <xsl:element name="date">
    <!--
         ** Call this template when you want to reverse the date **
    -->
    <xsl:call-template name="reverse-date">
     <xsl:with-param name="text" select="@date" />
    </xsl:call-template>
  </xsl:element>
</xsl:template>

<xsl:template name="reverse-date">
    <xsl:param name="text" select="."/>
    <xsl:choose>
        <xsl:when test="contains($text, '-')">
           <xsl:value-of select="substring-before($text, '-')" />
            <xsl:text>-</xsl:text>
            <xsl:call-template name="reverse-date">
                <xsl:with-param name="text" select="substring-after($text, '-')"/>
            </xsl:call-template>
        </xsl:when>
        <xsl:otherwise>
           <xsl:value-of select="normalize-space($text)"/>
        </xsl:otherwise>
    </xsl:choose>
</xsl:template>
</xsl:stylesheet>
