    </xsl:template> 

</xsl:stylesheet> 

在輸出XML文檔我想要的價值xmlns：PREMIS將更改爲「http://www.loc.gov/premis/rdf/v1#」。所以開頭的根元素應該看起來像這樣：

<rdf:RDF xmlns:PREMIS="info:lc/xmlns/premis-v2" 
xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" 
xmlns:dc="http://purl.org/dc/elements/1.1/" 
xmlns:xlink="http://www.w3.org/1999/xlink"> 

我已經嘗試了幾件事，我在這裏也發現了一些帖子。但我不明白。有任何想法嗎？謝謝。

後處理XSLT：

<?xml version="1.0"?> 
<!-- sample_2.xsl --> 
<xsl:stylesheet version="2.0" 
exclude-result-prefixes="PREMIS" 
xmlns:PREMIS="info:lc/xmlns/premis-v2" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" 
xmlns:dc="http://purl.org/dc/elements/1.1/" 
xmlns:xlink="http://www.w3.org/1999/xlink" xlink:type="simple" 
> 

<xsl:template match="*"> 
    <xsl:copy> 
     <xsl:copy-of select="namespace::* except namespace::PREMIS"/> 
     <xsl:namespace name="PREMIS" select="'http://www.loc.gov/premis/rdf/v1#'"/> 
     <xsl:copy-of select="@*"/> 
     <xsl:apply-templates/> 
    </xsl:copy> 
</xsl:template> 

<xsl:template match="PREMIS:*"> 
    <xsl:element name="PREMIS:{local-name()}" namespace="http://www.loc.gov/premis/rdf/v1#"> 
     <xsl:copy-of select="namespace::* except namespace::PREMIS"/> 
     <xsl:copy-of select="@*"/> 
     <xsl:apply-templates/> 
    </xsl:element> 
</xsl:template></xsl:stylesheet> 

Answer 1

我假設你想要的輸出是一個錯字，而你真正想要的：

<rdf:RDF xmlns:PREMIS="http://www.loc.gov/premis/rdf/v1#" 
xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" 
xmlns:dc="http://purl.org/dc/elements/1.1/" 
xmlns:xlink="http://www.w3.org/1999/xlink"> 
    ... 
</rdf:RDF> 

在你的樣式表，使用相同的前綴PREMIS參考不同的名稱空間取決於你是否正在閱讀或寫作將會非常困難。輸出中的前綴是否必須是PREMIS，還是會有其他前綴？如果它必須是相同的（也許無論如何），我認爲我的首選方法是後處理輸出使用：

<xsl:stylesheet exclude-result-prefixes="PREMIS"...> 

<xsl:template match="*"> 
    <xsl:copy> 
    <xsl:copy-of select="namespace::* except namespace::PREMIS"/> 
    <xsl:namespace name="PREMIS" select="'http://www.loc.gov/premis/rdf/v1#'"/> 
    <xsl:copy-of select="@*"/> 
    <xsl:apply-templates/> 
    </xsl:copy> 
</xsl:template> 

<xsl:template match="PREMIS:*"> 
    <xsl:element name="PREMIS:{local-name()}" namespace="http://www.loc.gov/premis/rdf/v1#"> 
    <xsl:copy-of select="namespace::* except namespace::PREMIS"/> 
    <xsl:copy-of select="@*"/> 
    <xsl:apply-templates/> 
    </xsl:element> 
</xsl:template>
