Hi,

I am having problem sorting on child-nodes (Article elements).
I would like to sort Article elements instead of Document elements
(below), by state-attribute. State is an integer.

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

       <xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>

       <xsl:template match="/">
               <Documents>
                       <xsl:apply-templates select="Documents/Document">
                               <xsl:sort select="@state" order="ascending"/>
                       </xsl:apply-templates>
               </Documents>
       </xsl:template>

       <xsl:template match="/Documents/Document">
               <xsl:copy>
                               <!-- I need sorting on this level -->
                               <xsl:copy-of select="@* | Article[@info = 'food']"/>
               </xsl:copy>
       </xsl:template>
</xsl:stylesheet>

<xsl:sort select="@title" order="ascending"/>

Can you please post your XML file. Could you please just elaborate more on the specifics of what you want to sort, thanks.

Beside the filtering part already done in the XSLT,
what I want to sort is elements that contain attribute state. I would like to sort Article elements by state-attribute in the acesending order.

XML file:

<Documents>
       <Document title="1" chapter="1" href="file1.xml" filter="food">
               <Article title="1.1" info="sub" filter="food" state="1"/>
               <Article title="1.2" info="main" filter="food" state="3"/>
       </Document>
       <Document title="2" chapter="2" href="file2.xml" filter="drink">
               <Article title="2.1" info="sub" filter="drink" state="4"/>
               <Article title="2.2" info="main" filter="food" state="2"/>
       </Document>
       <Document title="3" chapter="3" href="file2.xml" filter="">
               <Article title="3.1" info="sub" filter="drink" state=""/>
               <Article title="3.2" info="child" filter="" state="8"/>
       </Document>
</Documents>

Did you want to output an XML file or just plain text like so:

<Article title="2.2" info="main" filter="food" state="2"/>
<Article title="1.2" info="main" filter="food" state="3"/>
<Article title="2.1" info="sub" filter="drink" state="4"/>
<Article title="1.1" info="sub" filter="food" state="1"/>
<Article title="3.1" info="sub" filter="drink" state="7"/>
<Article title="3.2" info="child" filter="food" state="8"/>

Also, did you want to do 2 sorts? Becaues in your question you indicate that you want to sort by title attributes:

<xsl:sort select="@title" order="ascending"/>

And on another line you indicate this:

<!-- I need sorting on this level -->
<xsl:copy-of select="@* | Article[@info = 'food']"/>

And then on another line:

<xsl:sort select="@state" order="ascending"/>

<!-- I need sorting on this level -->
<xsl:copy-of select="@* | Article[@info = 'food']"/>

all other functions except sorting are supposed to be left there. i need to add sorting on Article level.
dissregard sorting on Document level. it is not necessary. Only Article level (sort-by state) is needed.

thanx.

This XSLT will sort the articles by @state.  I do it in a for-each loop that selects all articles.  If you do it inside an apply-templates, then it will only sort the children of the current element.  If you want to sort all the articles, it have to grab all of them in a single pass.

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>

<xsl:template match="Documents">
       <Documents>
           <xsl:for-each select="Document/Article">
                        <xsl:sort select="@state" order="ascending"/>
                        <xsl:apply-templates select="."/>
           </xsl:for-each>
       </Documents>
</xsl:template>

<xsl:template match="Article">
        <xsl:copy>
                 <xsl:copy-of select="@* | Article[@info = 'food']"/>
        </xsl:copy>
</xsl:template>

</xsl:stylesheet>


Produces...

<Documents>
  <Article title="3.1" info="sub" filter="drink" state=""></Article>
  <Article title="1.1" info="sub" filter="food" state="1"></Article>
  <Article title="2.2" info="main" filter="food" state="2"></Article>
  <Article title="1.2" info="main" filter="food" state="3"></Article>
  <Article title="2.1" info="sub" filter="drink" state="4"></Article>
  <Article title="3.2" info="child" filter="" state="8"></Article>
</Documents>
