题
我有一些经验XSLT但是现在我有我自己一个问题:我需要检查如果一个期间之间开始和结束日期完全涵盖其他时期。
这里的一部分xml:
<Parent ID="1">
<StartDate>20050101</StartDate>
<EndDate>20060131</EndDate>
<Child ID="1">
<StartDate>20050101</StartDate>
<EndDate>20081231</EndDate>
</Child>
</Parent>
<Parent ID="2">
<StartDate>20060201</StartDate>
<EndDate>20071231</EndDate>
<Child ID="1">
<StartDate>20050101</StartDate>
<EndDate>20081231</EndDate>
</Child>
</Parent>
<Parent ID="3">
<StartDate>20080101</StartDate>
<EndDate>20081231<EndDate>
<Child ID="1">
<StartDate>20050101</StartDate>
<EndDate>20081231</EndDate>
</Child>
</Parent>
所以我需要检查如果期间开始和结束的父母是完全涵盖的期间开始和结束儿童在XSLT写的父母和孩子ID的xml于失败。
有人能给我一个头开始如何管理这XSLT...?
我已经完全控制结构的XML因此,当它是更容易与其他XML结构(相同的数据)我可以改变它。
非常感谢!
解决方案
使用简单的字符串比较,这是很容易的,因为你的日期格式为大端。下面是我写来测试它的快速XSLT文件:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" indent="yes"/>
<xsl:template match="/">
<root>
<xsl:for-each select="//Parent">
<parent>
<xsl:attribute name="id">
<xsl:value-of select="@ID"/>
</xsl:attribute>
<xsl:choose>
<xsl:when test="(Child/StartDate <= StartDate) and
(Child/EndDate >= EndDate)">
<xsl:text>OK</xsl:text>
</xsl:when>
<xsl:otherwise>
<xsl:text>Not OK</xsl:text>
</xsl:otherwise>
</xsl:choose>
</parent>
</xsl:for-each>
</root>
</xsl:template>
</xsl:stylesheet>
显然,你需要自己检查,以确保StartDate
是EndDate
两个父母和孩子面前。
其他提示
下面是一个例子,以直接做在XSLT 2.0,并应与最日期定界符工作:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0"
exclude-result-prefixes="functx xs"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:functx="http://www.functx.com"
xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xsl:template match="/">
<dates>
<dateBetween>
<xsl:choose>
<xsl:when test="functx:dateBetween('02-01-2009','01-01-2009','03-01-2009')=true()">
<xsl:text>date lays between given dates</xsl:text>
</xsl:when>
<xsl:otherwise>
<xsl:text>date is not between given dates</xsl:text>
</xsl:otherwise>
</xsl:choose>
</dateBetween>
<currentDateBetween>
<xsl:choose>
<xsl:when test="functx:currentDateBetween('01-01-2000','01-01-2019')=true()">
<xsl:text>current date lays between given dates</xsl:text>
</xsl:when>
<xsl:otherwise>
<xsl:text>current date is not between given dates</xsl:text>
</xsl:otherwise>
</xsl:choose>
</currentDateBetween>
</dates>
</xsl:template>

什么是错的 number(Child/StartDate) <= number(Parent/StartDate) and number(Child/EndDate) >= number(Parent/EndDate)
?
