xml - XSLT - Trouble to filter parent nodes by its childs using a configuration node -

-

i have situation in xsl can't figure out how resolve.

i have following xml, , want show main nodes have @ least 1 item enabled config/enable-items nodes.

any hints?

thanks in advance.

xml: 

<xml>  <main name="main section 1" id="1">     <item id="a">     </item>     <item id="b">     </item>     <item id="c">     </item> </main>  <main name="main section 2" id="2">     <item id="d">     </item>     <item id="e">     </item>     <item id="f">     </item> </main>  <config>     <enable-items>         <item id="a" />         <item id="b" />     </enable-items> </config>  </xml>

wanted output:

main section 1:     *     * b

p.s.: i've tried using key, defining key enable-items indexed id attribute, , doing for-each on items define variable ... no luck, :(, still don't know how check items inside main before showing main @name attribute ...

well,

i trying using more complex xml, on real world application. when did example post here, managed working :)

follow answer:

<?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/xsl/transform">  <xsl:key name="enable-items" match="config/enable-items/item" use="@id"/> <xsl:template match="/xml"> <xsl:apply-templates select="main" />   </xsl:template>  <xsl:template match="main">     <xsl:if test="key('enable-items', item/@id)">          <h1><xsl:value-of select="@name"/> </h1>                  <xsl:for-each select="key('enable-items', item/@id)">                <xsl:value-of select="@id" /> <br>               </xsl:for-each>     </xsl:if> </xsl:template>  </xsl:stylesheet>

i'm using transactionscope rollback transaction fail bool errorreported = false; action<importerrorlog> newerrorcallback = e => { errorreported = true; errorcallback(e); }; using (var transaction = new transactionscope()) { foreach (importtaskdefinition task in taskdefinition) { loader.load(streamfile, newerrorcallback, task.destinationtable, processingtaskid); } if (!errorreported) transaction.complete(); } i'm sure there no transactionscope started ahead or after code. i'm using entity framework insert in db. regardless state of errorreported transaction never rolled in case of error. what missing ? transactionscope sets transaction.current . that's does. wants transacted must @ property. i believe ef each time connection opened reason. probably, connection open when scope installed. open connection inside of scope or enlist manually. ef has nasty "design decision": default opens
