特定条件下的 XSLT 1.0 转换答案

【问题标题】：XSLT 1.0 transformation under certain conditions特定条件下的 XSLT 1.0 转换

【问题描述】：

我有一个 xml，它是几个子系统查询的合并输出。现在我必须挑选很多信息。例如：

/合并/响应/BenutzerDaten/Deaktiviert

如果 /Merge/response/results/result/dn 以 ",o=test,c=de" 结尾，并且只有一个结果以该模式结尾：

/Merge/response/results/result/attributes/identnummer

如果 /Merge/response/results/result/dn 以“,DC=TEST,DC=DE”结尾：

/Merge/response/results/result/attributes/postalCode

最好的方法是什么？

这是我的原始 xml 的简化示例：

<?xml version="1.0" encoding="UTF-8"?>
<Merge>
    <response>
        <results>
            <result>
                <dn>cn=user1,ou=members,ou=group1,o=test,c=de</dn>
                <attributes>
                    <identnummer>re3232</identnummer>
                    <uid>user1</uid>
                    [...]
                    <adminuid>admin3</adminuid>
                </attributes>
            </result>
        </results>
    </response>
    <response>
        <results>
            <result>
                <dn>CN=user1,OU=Users,DC=TEST,DC=DE</dn>
                <attributes>
                    <postalCode>12345</postalCode>
                    <company>My Company</company>
                    [...]
                    <streetAddress>XSLT Road 1</streetAddress>
                </attributes>
            </result>
        </results>
    </response>
    <response>
        <secDN>principalName=user1,cn=Users,secDomain=Default</secDN>
        <Benutzerdaten>
            <Deaktiviert>false</Deaktiviert>
            <Gesperrt>false</Gesperrt>
            [...]
            <PasswortGueltig>true</PasswortGueltig>
        </Benutzerdaten>
    </response>
    <Nutzdaten>
        <Identifikation>
            <AdminID>admin3</AdminID>
            <BenutzerID>user1</BenutzerID>
        </Identifikation>
        <Benutzerdaten>
            <Datentyp>Account-Daten</Datentyp>
            <Datentyp>Anwendungs-Daten</Datentyp>
            <Datentyp>Benutzer-Daten</Datentyp>
        </Benutzerdaten>
    </Nutzdaten>
</Merge>

预期结果应如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<UserData>
    <user>user1</user>
    <source1>
        <identnummer>re3232</identnummer>
    </source1>
    <source2>
        <postalCode>12345</postalCode>
    </source2>
    <source3>
        <Deaktiviert>false</Deaktiviert>
    </source3>
</UserData>

这是我失败的尝试：

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:template match="/">

          <xsl:if test="substring(/Merge/response/results/result/dn, string-length(/Merge/response/results/result/dn) -11) = ',o=test,c=de'">

                </postalCode>
            </source1>
          </xsl:if>
          <xsl:if test="substring(/Merge/response/results/result/dn, string-length(/Merge/response/results/result/dn) -12) = ',DC=TEST,DC=DE'">

【解决方案1】：

试试下面的：

    <xsl:param name="text" select="/Merge/response/results/result/dn[contains(text(),'o=test,c=de')]"/>
    <xsl:param name="text1" select="/Merge/response/results/result/dn[contains(text(),'DC=TEST,DC=DE')]"/>
    <xsl:choose>
        <xsl:when test="/Merge/response/Benutzerdaten and count(/Merge/response/results/result/dn [contains(text(),'o=test,c=de')]) = 1 and count(/Merge/response/results/result/dn[contains(text(),'DC=TEST,DC=DE')]) = 1" >
