Passando parâmetros para XSLT Stylesheet via .NET

Pergunta
Eu estou tentando passar um parâmetro para uma folha de estilo XSLT, mas tudo que eu estou recebendo é um documento XML vazio quando o documento é transformado usando XslCompiledTransform.
Este é o método C # usado para adicionar os parâmetros (depois de adicionar em sugestões das pessoas)
private static void CreateHierarchy(string manID)
{
string man_ID = manID;
XsltArgumentList argsList = new XsltArgumentList();
argsList.AddParam("Boss_ID","",man_ID);
XslCompiledTransform transform = new XslCompiledTransform();
transform.Load("htransform.xslt");
using (StreamWriter sw = new StreamWriter("output.xml"))
{
transform.Transform("LU AIB.xml", argsList, sw);
}
}
e aqui é a folha de estilo. O parâmetro que eu estou passando é 'Boss_ID'
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="xml" indent="yes" />
<xsl:template match="OrgDoc">
<xsl:param name="Boss_ID"></xsl:param>
<xsl:processing-instruction name="xml-stylesheet">
<xsl:text>type="text/xsl" href="..\styles\orgcharts.xsl" </xsl:text>
</xsl:processing-instruction>
<OrgDoc>
<xsl:for-each select="PosDets[@OC_Man = $Boss_ID]">
<PosDets OC_Pos="{@OC_Pos}" OC_Sub="{@OC_Sub}" OC_Man="{@OC_Man}" OC_Ttl="{@OC_Ttl}" OC_Rnk="{@OC_Rnk}" OC_Bdg="{@OC_Bdg}" OC_Fnd="{@OC_Fnd}" OC_OL3="{@OC_OL3}" OC_Tmp="{@OC_Tmp}">
<xsl:apply-templates select="../PosDets">
<xsl:with-param name="mgrid" select="@OC_Pos"/>
</xsl:apply-templates>
</PosDets>
</xsl:for-each>
</OrgDoc>
</xsl:template>
<xsl:template match="PosDets" >
<xsl:param name="mgrid" />
<xsl:if test="@OC_Man=$mgrid" >
<PosDets OC_Pos="{@OC_Pos}" OC_Sub="{@OC_Sub}" OC_Man="{@OC_Man}" OC_Ttl="{@OC_Ttl}" OC_Rnk="{@OC_Rnk}" OC_Bdg="{@OC_Bdg}" OC_Fnd="{@OC_Fnd}" OC_OL3="{@OC_OL3}" OC_Tmp="{@OC_Tmp}">
<xsl:apply-templates select="../PosDets">
<xsl:with-param name="mgrid" select="@OC_Pos"/>
</xsl:apply-templates>
</PosDets>
</xsl:if>
</xsl:template>
</xsl:stylesheet>
Eu não posso postar tudo do documento de entrada como é informação confidencial, mas aqui está uma breve versão higienizado
<OrgDoc><PosDets OC_Pos="161" OC_Man="9" OC_Ttl="Boss" OC_Rank="" OC_OL3="LU AIB" OC_Bdg="Has Budget" OC_Fnd="Payroll" OC_Sub="" OC_Tmp="" /><PosDets OC_Pos="190" OC_Man="161" OC_Ttl="Boss" OC_Rank="" OC_OL3="LU AIB" OC_Bdg="Has Budget" OC_Fnd="Payroll" OC_Sub="" OC_Tmp="" /><PosDets OC_Pos="199" OC_Man="190" OC_Ttl="Boss" OC_Rank="" OC_OL3="LU AIB" OC_Bdg="Has Budget" OC_Fnd="Payroll" OC_Sub="" OC_Tmp="" /></OrgDoc>
alguém pode ajudar?
Graças
Solução
You need to define the parameter within your XSLT and you also need to pass the XsltArgumentList
as an argument to the Transform
call:
private static void CreateHierarchy(string manID)
{
string man_ID = manID;
XsltArgumentList argsList = new XsltArgumentList();
argsList.AddParam("Boss_ID", "", man_ID);
XslCompiledTransform transform = new XslCompiledTransform(true);
transform.Load("htransform.xslt");
using (StreamWriter sw = new StreamWriter("output.xml"))
{
transform.Transform("LU AIB.xml", argsList, sw);
}
}
Please note that the xsl:param
must be defined below the xsl:stylesheet
element:
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="xml" indent="yes" />
<xsl:param name="Boss_ID"></xsl:param>
<xsl:template match="OrgDoc">
<!-- template body goes here -->
</xsl:template>
</xsl:stylesheet>
This simple XSLT sample will create just a small output document containing one XML node with its contents set to the value of your parameter. Have a try:
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="xml" indent="yes" />
<xsl:param name="Boss_ID"></xsl:param>
<xsl:template match="/">
<out>
<xsl:value-of select="$Boss_ID" />
</out>
</xsl:template>
</xsl:stylesheet>
Outras dicas
you probably need to define the param at the top of the XSLT:
<xsl:param name="Boss_ID" />
<OrgDoc>
//rest of the XSLT
</OrgDoc>

Not a great example but the best I could find with a quick google.
