任何人都可以帮助我理解这个XSL的东西 [英] can any one help me to understand this XSL stuff

问题描述

我的一个XSLT页面包含这个代码，任何人都可以帮助我理解它将返回什么。





< pre lang =xml> < xsl：if test = string-length（DMS_Document / Payload / DMS_DispatchResponse /消息/供应商）！= 0 >
< xsl：element name < span class =code-keyword> = VENDOR_ID >
< xsl：value-of 选择 = number（DMS_Document / Payload / DMS_DispatchResponse / Message / Vendor） / >
< / xsl：element >

疑问1：此代码是否始终将供应商作为数字返回。 
 2：或者它将返回DMS_Document / Payload / DMS_DispatchResponse / Message / Vendor中的内容

提前感谢

解决方案

为什么不测试它和检查结果？看一下你可以在codeproject上找到的工具：

（非常）简单的XSLT测试实用程序 [ ^ ]



或在线试用：

祝你好运！

它总是将供应商作为号码给予

 number（DMS_Document / Payload / DMS_DispatchResponse / Message / Vendor）
 
 
& lt; pre lang =& quot; xml& quot;& gt ;& amp; lt; xsl：if test =& amp; quot; string-length（DMS_Document / Payload / DMS_DispatchResponse / Message / Vendor）！= 0& amp; quot;& amp; gt; 
& amp; lt; xsl：element name =& amp; quot; VENDOR_ID& amp; quot;& amp; gt; 
& amp; lt; xsl：value-of select =& amp; quot; number（DMS_Document / Payload / DMS_DispatchResponse / Message / Vendor）& amp; quot; /& amp; gt; 
& amp; lt; / xsl：element& amp; gt;& lt; / pre& gt; <   / pre  >  

one of my XSLT page contains this code, can any one help me to understand what exactly it will return.

<xsl:if test="string-length(DMS_Document/Payload/DMS_DispatchResponse/Message/Vendor) != 0">
                            <xsl:element name="VENDOR_ID">
                                <xsl:value-of select="number(DMS_Document/Payload/DMS_DispatchResponse/Message/Vendor)"/>
                            </xsl:element>

Doubt 1: will this code always return Vendor as number.
2:  or it will return what is there in DMS_Document/Payload/DMS_DispatchResponse/Message/Vendor

thanks in advance

解决方案

Why not test it amd check the results? Have a look at a tool you can find here on codeproject:
A (very) simple XSLT test utility[^]

Or try it online:
http://xslttest.appspot.com/[^]

Good luck!

it will always give the Vendor as number due to

number(DMS_Document/Payload/DMS_DispatchResponse/Message/Vendor)


<pre lang="xml"><xsl:if test="string-length(DMS_Document/Payload/DMS_DispatchResponse/Message/Vendor) != 0">
                            <xsl:element name="VENDOR_ID">
                                <xsl:value-of select="number(DMS_Document/Payload/DMS_DispatchResponse/Message/Vendor)"/>
                            &amp;lt;/xsl:element&amp;gt;&lt;/pre&gt;</pre>
