我想獲得一些幫助，下面的問題：

  1. 有一個不需要的xmlns =「」元素中不能使用排除-result-被刪除輸出前綴屬性。我不知道如何擺脫它。

  2. 樣式表有兩個長XPath。他們完成這項工作並指出了正確的元素，但每次看到它們時，我都忍不住c咽。如果有人可以提供更短，更清潔的替代品，我會非常感激。

簡化的XPath

我建議你，包括您的轉換前綴爲默認命名空間的聲明。例如，對於

<SearchDocumentsResult xmlns="http://worksite.imanage.com">

你可以在樣式表元素添加w前綴：

<xsl:stylesheet 
xmlns:xsl = "http://www.w3.org/1999/XSL/Transform" 
xmlns:xs = "http://www.w3.org/2001/XMLSchema" 
xmlns:soap = "http://www.w3.org/2003/05/soap-envelope" 
xmlns:w = "http://worksite.imanage.com" 
exclude-result-prefixes="#all" 
version="2.0">

爲您選擇了命名空間的元素這將使更加容易，從而能夠避免對namespace-uri() XPath的比賽，並簡化你的XPath。

關於XPath，您的選擇必須是絕對的？例如，下面的工作一樣對我來說：

"/soap:Envelope/soap:Body[1]/w:SearchDocumentResult/*[1]/*[1]/*[1]/*[6]/*[1]"

但你也可以使用：

"/soap:Envelope/soap:Body[1]/w:SearchDocumentResult//w:Value[1]"

刪除空命名空間

爲了擺脫出現空命名空間在Value元素中，您需要修正樣式表，以便每個Value元素都正確地位於第e命名空間。例如：

<xsl:when test="$iManageExtension eq 'ACROBAT'"> 
    <xsl:element 
     name="Value" 
     namespace="http://worksite.imanage.com"> 
     pdf 
    </xsl:element>

通過這種方式，系統通常會輸出沒有命名空間的元素。

關於簡化的XPath還注意到

注意在某些情況下，其中大部分是要管理一個特定的命名空間，你可以簡單地做：

<xsl:stylesheet 
xmlns:xsl = "http://www.w3.org/1999/XSL/Transform" 
xmlns:xs = "http://www.w3.org/2001/XMLSchema" 
xmlns:soap = "http://www.w3.org/2003/05/soap-envelope" 
exclude-result-prefixes="#all" 
xpath-default-namespace="http://worksite.imanage.com" 
version="2.0">

和沒有命名空間前綴。

感謝您的建議。使用關於默認名稱空間的提示，我可以簡化兩個XPath。但我仍然不知道如何擺脫出現在輸出中的xmlns =「」。 – 2011-06-07 07:06:37
