Sorting Elements

[scopley]

I have written an XSL script and everything works great except the sorting. I need the data to sort by <prtnbr> but cannot accomplish this unless I remove 2 columns of required data that is generated by attributes.Here is a sample of the XML file:

<chapter chapnbr="23" id="ch23"><section chapnbr="23" id="sc2320" sectnbr="20"><subject chapnbr="23" id="sj232000" sectnbr="20" subjnbr="00"><dpfigure chg="u" figcnt="10" id="sj23200010"><prtlist><prtrow><item>005</item><prtnbr>822-1071-001</prtnbr><qty>1</qty></prtrow><prtrow><item>010</item><prtnbr>372254-91</prtnbr><qty>1</qty></prtrow><prtrow><item>015</item><prtnbr>372254-93</prtnbr><qty>1</qty></prtrow><prtrow><item>020</item><prtnbr>622-4957-001</prtnbr><qty>1</qty></prtrow></prtlist></dpfigure></subject><subject chapnbr="23" id="sj232000" sectnbr="20" subjnbr="10"><dpfigure chg="u" figcnt="20" id="sj23200010"><prtlist><prtrow><item>105</item><prtnbr>1071-001</prtnbr><qty>1</qty></prtrow><prtrow><item>015</item><prtnbr>72254-91</prtnbr><qty>1</qty></prtrow><prtrow><item>025</item><prtnbr>3254-93</prtnbr><qty>1</qty></prtrow><prtrow><item>030</item><prtnbr>62-4957-001</prtnbr><qty>1</qty></prtrow></prtlist></dpfigure></subject><subject chapnbr="23" id="sj232000" sectnbr="20" subjnbr="20"><dpfigure chg="u" figcnt="30" id="sj23200010"><prtlist><prtrow><item>005</item><prtnbr>MK1071-001</prtnbr><qty>1</qty></prtrow><prtrow><item>010</item><prtnbr>54AB-91</prtnbr><qty>1</qty></prtrow><prtrow><item>015</item><prtnbr>3254-LO</prtnbr><qty>1</qty></prtrow><prtrow><item>020</item><prtnbr>JT-4957-001</prtnbr><qty>1</qty></prtrow></prtlist></dpfigure></subject></section></chapter>

Here is part of the XSL file:

<xsl:apply-templates select="//subject">	<xsl:sort select="prtnbr"></xsl:apply-templates><xsl:template match="subject">  <xsl:variable name="chsecsub">	<xsl:value-of select="@chapnbr"/>	<xsl:text>-</xsl:text>	<xsl:value-of select="@sectnbr"/>	<xsl:text>-</xsl:text>	<xsl:value-of select="@subjnbr"/>  </xsl:variable>  <xsl:for-each select="dpfigure">	<xsl:variable name="figcnt" select="@figcnt"/>	<xsl:for-each select="prtlist/prtrow">	<fo:table-row>	<fo:table-cell>	<fo:block>		<xsl:value-of select="prtnbr"/>	</fo:block>	</fo:table-cell>	<fo:table-cell>	<fo:block>		<xsl:value-of select="$chsecsub"/>	</fo:block>	</fo:table-cell>	<fo:table-cell>	<fo:block>		<xsl:value-of select="$figcnt"/>	</fo:block>	</fo:table-cell>	<fo:table-cell text-align="center">	<fo:block>		<xsl:value-of select="item"/>	</fo:block>	</fo:table-cell>	<fo:table-cell>	<fo:block>		<xsl:value-of select="qty"/>	</fo:block>	</fo:table-cell>	</fo:table-row>	</xsl:for-each>	</xsl:for-each>	</xsl:template>

Here is the desired output:

Part Number        Ch/Sec/Sub        Fig.        Item        Qty.1071-001             23-20-10           20           105           13254-93               23-20-10           20          025            13254-LO               23-20-20          30          015             1372254-91           23-20-00           10           010           1372254-93           23-20-00           10           015          154AB-91              23-20-20           30           010          1622-4957-001      23-20-00           10           020          1623-4957-001      23-20-10           20           030          172254-91            23-20-10           20           015          1822-1071-001     23-20-00            10          005           1JT-4957-001        23-20-20          30           020            1MK1071-001        23-20-20          30           005            1

Any help would be greatly appreciated as I have been struggling with this for several days now.

Problem has been solved by using the axes nodes. The following is a simplified version of the code:

<xsl:template match="chapter">   <xsl:for-each select="descendant::prtrow">     <xsl:sort select="prtnbr" />     <row>       <cell><xsl:value-of select="ancestor::chapter/@chapnbr"/></cell>       <cell><xsl:value-of select="item"/></cell>       <cell><xsl:value-of select="prtnbr"/></cell>     <row>   </xsl:for-each></xsl:template>
