XSL if else 条件 [英] XSL if else condition

问题描述

我有一个要求，我希望使用 if else 语句来检查节点是否具有属性或只有字符串.

I have a requirement where I'd like to have if else statement to check whether a node has attributes or it has just string.

例如:节点的 1 个具有 0 文件找到，另一个节点具有诸如 <autoincludesystem_info mdate='08/23/2011' mtime='09 的属性:51'ampm​​='PM'filesize='64'filename='AFP_p.tgp'/>

Eg: 1 of the node has 0 File(s) found and the other has attribs such as <autoincludesystem_info mdate='08/23/2011' mtime='09:51' ampm='PM' filesize='64' filename='AFP_p.tgp' />

下面是两个节点的示例

<product>
<autoIncludeUser>0 File(s) found</autoIncludeUser>
<autoIncludeSystem>
<autoincludesystem_info mdate='08/23/2011' mtime='09:51' ampm='PM' filesize='64' filename='AFP_p.tgp' />
<autoincludesystem_info mdate='08/23/2011' mtime='09:51' ampm='PM' filesize='3,879' filename='AnalystsExpressionMacros.tgp' />
<autoincludesystem_info mdate='08/23/2011' mtime='09:51' ampm='PM' filesize='475' filename='base64Converter.tgp' />
<autoincludesystem_info mdate='08/23/2011' mtime='09:51' ampm='PM' filesize='&lt;DIR&gt;' filename='codePages' />
</autoIncludeSystem>
<autoIncludeStudio>0 File(s) found</autoIncludeStudio>
<externalLibrarySystem>
<externalLibrarySystem_info mdate='08/23/2011' mtime='09:52' ampm='PM' filesize='196,608' filename='AFPtoXML_DP.dll' />
<externalLibrarySystem_info mdate='08/23/2011' mtime='09:52' ampm='PM' filesize='13,259' filename='ASN1toXSDRunner.jar' />
<externalLibrarySystem>
</product>

我如何确定节点是否只有字符串或属性，并基于此我可以分别获得 String 或 attrib 值 的值.

How would i identify if a node has just strings or attribs and based on that I can get the values either String or attrib values respectively.

推荐答案

您可以将整个 xsl:choose 指令替换为:

You can replace your whole xsl:choose instruction with:

<xsl:apply-templates select="autoIncludeSystem"/>

然后添加两个模板:

<xsl:template match="autoIncludeSystem[autoincludesystem_info/@*]>
  <!-- code for elements with attributes (xsl:when) -->
</xsl:template>


<xsl:template match="autoIncludeSystem[not(autoincludesystem_info/@*)]>
  <!-- code for elements without attributes (xsl:otherwise) -->
</xsl:template>
