使用XSLT增加元素值

Iam坚持使用xslt递增值。我需要根据特定条件增加元素值。在实际xml中，每个策略/ PolicyConditions都满足，我需要增加1并创建policy / PolicyConditions / PolicyConditionCriteria / ItemData。请查看预期的xml以获取详细信息。

输入XML：

    <buildings>
    <building>
                <building-header>
                    <location-number>LU1</location-number>
                    <building-number>LU1-B1</building-number>
                </building-header>
    </building> 
    <building>
                <building-header>
                    <location-number>LU2</location-number>
                    <building-number>LU2-B1</building-number>
                </building-header>
    </building>
    <building>
                <building-header>
                    <location-number>LU2</location-number>
                    <building-number>LU2-B2</building-number>
                </building-header>
    </building>
    <building>
                <building-header>
                    <location-number>LU3</location-number>

您可以在此处使用密钥以building

查找location-number个元素 
<xsl:key name="buildings" match="building" use="building-header/location-number" />

现在，您可以使用position()生成所需的数字，但为了实现此目的，您必须为一个覆盖范围内的所有building选择insured-object元素选择陈述。

 <xsl:variable name="insured-objects" select="location-rule/insured-objects/insured-object/insured-object-nr" />
 <xsl:for-each select="key('buildings', $insured-objects)">

我还注意到，当两个xsl:if语句之间的唯一区别似乎是生成Name元素时，XSLT中似乎有很多重复。

试试这个XSLT 

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes" omit-xml-declaration="yes"/>

<xsl:key name="buildings" match="building" use="building-header/location-number" />

<xsl:template match="/">
    <policy>
        <xsl:for-each select="//coverage">
            <PolicyConditions>
                <xsl:variable name="code" select="limit/limit-type/@code" />
                <xsl:variable name="count" select="count(preceding-sibling::coverage[limit/limit-type/@code = $code]) + 1" />
                <Name>
                    <xsl:choose>
                        <xsl:when test="$code='Bla'">EQ Blanket</xsl:when>
                        <xsl:when test="$code='Sub'">EQ Sublimit</xsl:when>
                    </xsl:choose>
                    <xsl:value-of select="$count" />
                </Name>
                <Item>
                    <xsl:value-of select="$count" />
                </Item>
                <xsl:variable name="insured-objects" select="location-rule/insured-objects/insured-object/insured-object-nr" />
                <xsl:for-each select="key('buildings', $insured-objects)">
                    <PolicyConditionCriteria>
                        <Field>LOCNAME</Field>
                        <Value>
                            <xsl:value-of select="building-header/building-number"/>
                        </Value>
                        <ItemData>
                            <xsl:value-of select="position()" />
                        </ItemData>
                    </PolicyConditionCriteria>
                </xsl:for-each>
            </PolicyConditions>
        </xsl:for-each>
    </policy>
</xsl:template>
</xsl:stylesheet>
