XSLT問題比較兩個XPath和轉換XML

我需要通過比較兩個不同的XPath創建一個XSLT和兩個孩子小號獲得價值和轉換XML。XSLT問題比較兩個XPath和轉換XML

規則如下：

1.)I need to compare the location-number inside buildings/building/building-header/location-number with buildings/policy/coverages/coverage/location-rule/insured-objects/insured-object/insured-object-nr and for the locations not matching i need to create element Policy/PolicyConditions/Name as No coverage and map the Policy/PolicyConditions/PolicyConditionCriteria/Value as the building-number ie.,LU4-B1 in my below example. 

2.)for each buildings/policy/coverages/coverage check for limit/limit-type/@code is Bla and for each location-rule/insured-objects/insured-object/insured-object-nr check for location-number inside buildings/building/building-header/location-number and get the 
buildings/building/building-header/building-number create Policy/PolicyConditions/Name as EQ Blanket and map the Policy/PolicyConditions/PolicyConditionCriteria/Value as the building-number LU1-B1,LU1-B1,LU2-B2 

3.)for each buildings/policy/coverages/coverage check for limit/limit-type/@code is Sub and for each location-rule/insured-objects/insured-object/insured-object-nr check for location-number inside buildings/building/building-header/location-number and get the 
buildings/building/building-header/building-number create Policy/PolicyConditions/Name as EQ Sublimit and map the Policy/PolicyConditions/PolicyConditionCriteria/Value as the building-number LU2-B1,LU2-B2,LU3-B1,LU3-B2 

Rule 2 and 3 are more or less the same only check that is different is with the limit/limit-type/@code.

亞姆能夠acheive規則2和規則3但不能夠寫入的邏輯來acheive規則1爲不匹配的XPath。

我僅可以使用XSLT版本1.0

輸入：

<buildings> 
<building> 
      <building-header> 
       <location-number>LU1</location-number> 
       <building-number>LU1-B1</building-number>

</building> 
<building> 
      <building-header> 
       <location-number>LU2</location-number>

          </insured-object>

這裏是一個解決方案：

     </policy> 
    </xsl:template> 
</xsl:stylesheet>

基本上，我添加了一個變量，其中我檢查是否存在與沒有相應的保險對象-NR的位置號碼。如果有的話，我在變量的值中添加字符串'true'。

然後，在模板中我檢查變量名，並再次檢查當前的位置，數量是否不具有相應的參保對象-NR。

感謝您的解決方案就幫助了很多。 – Ravi

親愛的瑪麗亞，我們發現，在這種方法的限制，該方法假設元素參保對象-NR和和位置號碼都位於一個獨特的XPATH。如果xml更改並且將來會有不同xpath的新元素具有相同名稱，那麼我們不會注意到這一點，並且會遇到錯誤。是否有其他選擇？ – Ravi

是的，您可以指定xpath，就像您在xslt的其他部分所做的一樣。我會編輯我的答案。 –
