我有一个要求，我想有if语句检查一个节点是否有属性或它只有字符串。
例如：节点的1具有找到的0个文件，并且另一个具有诸如< 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='<DIR>' 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>
如何识别一个节点是否只有字符串或属性，并且基于我可以分别获得字符串或attrib值。
您可以将整个xsl：choose指令替换为：
<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>
