多重條件在XSLT不工作

Question

我有下面的XML：

      <location_capability_category>1</location_capability_category> 
     </location_capability> 
    </location> 
    </bp> 

我必須採取1號線和在那裏「是第一性的能力」是真實地址2號線的「位置功能的能力」是HQ 。

在這種特殊情況下，我不應該得到line2中的任何內容，因爲地址沒有任何內容（對於滿足條件的上述地址）。不過，我的XSLT正在從下一個地址獲取第2行。這讓我相信我編碼的條件不起作用。儘管我在Line1中獲得了預期的輸出，但它只是因爲它是第一個地址。下面是我的XSLT：

<xsl:stylesheet version="1.0"  xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:fo="http://www.w3.org/1999/XSL/Format" xmlns:ns="http://target.com/2012/03/01/canonical/BusinessPartner"> 
<xsl:strip-space elements="*" /> 
<xsl:output method="text" version="1.0" encoding="UTF-8" indent="yes"/> 
<xsl:template match="/">bp_name|bp_id|line1|line2 
    <xsl:for-each select="ns:bp_list/ns:bp"> 
     <xsl:variable name="bp_name" select="normalize-space(ns:bp_name)"/> 
     <xsl:value-of select="$bp_name"/>|<xsl:value-of select="normalize-space(ns:bp_id)"/>|<xsl:if test="((ns:location/ns:bp_location/ns:bp_location_capability/ns:is_primary_capability = 'true') and (ns:location/ns:bp_location/ns:bp_location_capability/ns:location_function_capability_name = 'hq'))"> <xsl:value-of select="normalize-space(ns:location/ns:address/ns:line1)"/></xsl:if>|<xsl:if test="((ns:location/ns:bp_location/ns:bp_location_capability/ns:is_primary_capability = 'true') and (ns:location/ns:bp_location/ns:bp_location_capability/ns:location_function_capability_name = 'hq'))"> <xsl:value-of select="normalize-space(ns:location/ns:address/ns:line2)"/><xsl:text>&#xA;</xsl:text> 
    </xsl:for-each></xsl:template> 
</xsl:stylesheet> 

什麼可這裏的問題以及如何解決這個問題？

Answer 1

我認爲問題在於您正在檢查以查看某個地點是否符合您的條件，但您並未專門針對該地點。

您可以將條件移動到location上的謂詞，並僅輸出該位置的地址。
