xslt를 사용하여 문서에서 정렬하는 방법?

Question

아래 document_1.xml

<products> 
    <product> 
     <name>Pen</name> 
     <Quantity>30</Quantity> 
    </product> 
    <product> 
     <name>Pencil</name> 
     <Quantity>20</Quantity> 
    </product> 
    <product> 
     <name>Bag</name> 
     <Quantity>25</Quantity> 
    </product> 
</products> 

및 document_2.xml입니다

<products> 
    <product> 
     <name>Pen</name> 
     <Quantity>10</Quantity> 
    </product> 
    <product> 
     <name>Pencil</name> 
     <Quantity>5</Quantity> 
    </product> 
    <product> 
     <name>Bag</name> 
     <Quantity>2</Quantity> 
    </product> 
</products> 

및 document.xml 아래는

<products> 
</products> 

내 XSL은이다, 나는 document.xml

에 document_1.xml 및 document_2.xml에 가입하는 데 사용 51,515,

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

<xsl:template match="/products"> 
<xsl:copy> 
<xsl:apply-templates select="document('document_1.xml')/*/product"/> 
<xsl:apply-templates select="document('document_2.xml')/*/product"/> 
</xsl:copy> 
</xsl:template> 

<xsl:template match="@* | node()"> 
<xsl:copy> 
<xsl:apply-templates select="@* | node()"> 
</xsl:apply-templates> 
</xsl:copy> 
</xsl:template> 

</xsl:stylesheet> 

난 수량 ASC로

1. 아래 놓아 같은 출력을 필요

Answer 1

가 xsl:sort 태그이지만 xsl:for-each 루프 내에서만 사용될 수있다 - 예.

<xsl:for-each select="document('document_1.xml')/*/product|document('document_2.xml')/*/product"> 
    <xsl:sort select="Quantity" data-type="number" /> 
    ... 
</xsl:for-each>
