使用子字符串

标签： xslt-1.0

我的要求是通过一个日期来进行webservice调用，以便我获得自该日期以来已更改的所有记录。我正在使用Stylist Studio 2011进行开发。我设法得到一个减去2天的日期，但它总是返回一个时间：即2015-06-20-05：00但我只想要没有时间的日期。我已经尝试了substring，如下面的示例和日期格式，但我得到一个空结果。

此代码随时间返回：

{<?xml version='1.0' ?>
<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" 
xmlns:v1="http://types.msfc.nasa.gov/personnel/messages/v1/" 
xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"
xmlns:xs="http://www.w3.org/2001/XMLSchema" 
xmlns:fn="http://www.w3.org/2005/xpath-functions">
    <xsl:output method="xml" omit-xml-declaration="yes" indent="yes"/>
    <xsl:template match="/">
        <xsl:variable name="vToday" select="current-date()"/>

        <v1:lastChanged>
            <xsl:value-of select="$vToday -2*xs:dayTimeDuration('P1D')"/>
        </v1:lastChanged>
    </xsl:template>
</xsl:stylesheet>
}

结果是：

{
<v1:lastChanged xmlns:fn="http://www.w3.org/2005/xpath-functions" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:v1="http://types.msfc.nasa.gov/personnel/messages/v1/">2015-06-20-05:00</v1:lastChanged>
}

这是我的子串尝试

{<?xml version='1.0' ?>
<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" 
xmlns:v1="http://types.msfc.nasa.gov/personnel/messages/v1/" 
xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"
xmlns:xs="http://www.w3.org/2001/XMLSchema" 
xmlns:fn="http://www.w3.org/2005/xpath-functions">
    <xsl:output method="xml" omit-xml-declaration="yes" indent="yes"/>
    <xsl:template match="/">
        <xsl:variable name="vToday" select="current-date()"/>
        <xsl:variable name="vTodayTrim" select="$vToday -2*xs:dayTimeDuration('P1D')"/>
        <xsl:variable name="vTodayDate" fn:substring="(vTodayTrim,1 ,10)"/>
        <v1:lastChanged>
            <xsl:value-of select="vTodayDate"/>
        </v1:lastChanged>
    </xsl:template>
</xsl:stylesheet>
}

这是我的结果：

{`<v1:lastChanged xmlns:fn="http://www.w3.org/2005/xpath-functions" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:v1="http://types.msfc.nasa.gov/personnel/messages/v1/"/>`
}

我尝试了所有这些的多种变体，我能说的最好的是我得到了一致的结果。我此刻只追逐自己的故事。

我自己解决了这个问题。以下是现在的工作：

{
<?xml version='1.0' ?>
<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:mro="http://www.ibm.com/maximo"
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" 
xmlns:v1="http://types.msfc.nasa.gov/personnel/messages/v1/" 
xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"
xmlns:xs="http://www.w3.org/2001/XMLSchema" 
xmlns:fn="http://www.w3.org/2005/xpath-functions">
    <xsl:output method="xml" omit-xml-declaration="yes" indent="yes"/>
    <xsl:template match="/">
        <xsl:variable name="vToday" select="current-date()"/>
        <xsl:variable name="vTodayTrim" select="$vToday -2*xs:dayTimeDuration('P1D')"/>
        <v1:lastChanged>
            <xsl:value-of select="substring($vTodayTrim,1,10)"/>
        </v1:lastChanged>
    </xsl:template>
</xsl:stylesheet>
}

我回来了

{
<v1:lastChanged xmlns:fn="http://www.w3.org/2005/xpath-functions" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:mro="http://www.ibm.com/maximo" xmlns:v1="http://types.msfc.nasa.gov/personnel/messages/v1/">2015-06-20</v1:lastChanged>
}

所以我的新方法，因为我的应用程序不支持2.0是在xml中设置xml之前的值，如下所示（xml底部附近的lastChanged标记 - 这是在日志文件中输出） ：

{

}

当我在造型师工作室测试时，我的xslt似乎有效。这是当前的xslt 

{
<?xml version='1.0' ?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:mro="http://www.ibm.com/maximo" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:v1="http://types.msfc.nasa.gov/personnel/messages/v1/" xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:fn="http://www.w3.org/2005/xpath-functions">

            </v1:lastChanged>
        </v1:PersonQueryRequest>
    </xsl:template>
</xsl:stylesheet>
}

和stacktrace

这最后一种方法是正确的，在引用xsl调用时，我只是通过文件名来查找。这个问题已经解决了。
