xslt - Is it possible to build an XML document from a list of XPath values and the XML XSD? -

i have list of name/value pairs map xml document. idea this, assign each of names xpath this:

account_number       = 4294587576-32      = /my:myfields/my:customer/my:accountnumber customer_name        = john smith         = /my:myfields/my:customer/my:name customer_address     = tampa, fl  33604   = /my:myfields/my:customer/my:address amount_due           = 129.85             = /my:myfields/my:amountdue/my:amount days_past_due        = 54                 = /my:myfields/my:amountdue/my:dayspastdue 

now, shouldn't able take information along complete sample of xml document or xsd , build xml document looks this:

<my:myfields>     <my:customer>         <my:name>john smith</my:name>         <my:accountnumber>4294587576-32</my:accountnumber>         <my:address>tampa, fl  33604</my:address>     </my:customer>     <my:amountdue>         <my:dayspastdue>54</my:dayspastdue>         <my:amount>129.85</my:amount>     </my:amountdue> </my:myfields> 

my question specific microsoft infopath because need take list of name/value pairs , build xml data document infopath form. technology performs translation not have microsoft. java or c++ best solution. can done using xslt processor apache's xalan?

here 1 suggestion, mention java , xslt wouldn't bother xalan , xslt 1.0 instead use saxon 9 , xslt 2.0. assuming have well-formed xml input sample , above mapping of values xpath expressions feed mapping xslt 2.0 stylesheet generates second stylesheet can applied input sample. assuming have file 'test2011101201.txt' as

account_number       = 4294587576-32      = /my:myfields/my:customer/my:accountnumber customer_name        = john smith         = /my:myfields/my:customer/my:name customer_address     = tampa, fl  33604   = /my:myfields/my:customer/my:address amount_due           = 129.85             = /my:myfields/my:amountdue/my:amount days_past_due        = 54                 = /my:myfields/my:amountdue/my:dayspastdue 

the stylesheet

<xsl:stylesheet   xmlns:xsl="http://www.w3.org/1999/xsl/transform"   xmlns:axsl="http://www.w3.org/1999/xsl/transforma"   xmlns:xs="http://www.w3.org/2001/xmlschema"   xmlns:my="http://example.com/my"   version="2.0"   exclude-result-prefixes="xs">    <xsl:param name="text-file" as="xs:string" select="'test2011101201.txt'"/>   <xsl:variable name="lines" as="xs:string*" select="tokenize(unparsed-text($text-file), '\r?\n')[normalize-space()]"/>    <xsl:output method="xml" indent="yes"/>    <xsl:namespace-alias stylesheet-prefix="axsl" result-prefix="xsl"/>    <xsl:template match="/">     <axsl:stylesheet version="2.0">       <axsl:template match="@* | node()">         <axsl:copy>           <axsl:apply-templates select="@*, node()"/>         </axsl:copy>       </axsl:template>       <xsl:for-each select="$lines">         <xsl:variable name="tokens" select="tokenize(., '=')"/>         <axsl:template match="{normalize-space($tokens[3])}">           <axsl:copy>             <axsl:apply-templates select="@*"/>             <axsl:text>               <xsl:value-of select="replace($tokens[2], '(^\s+|\s+$)', '')"/>             </axsl:text>           </axsl:copy>         </axsl:template>       </xsl:for-each>     </axsl:stylesheet>   </xsl:template>  </xsl:stylesheet> 

can run produce second stylesheet

<?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/xsl/transform" xmlns:my="http://example.com/my"                 version="2.0">    <xsl:template match="@* | node()">       <xsl:copy>          <xsl:apply-templates select="@*, node()"/>       </xsl:copy>    </xsl:template>    <xsl:template match="/my:myfields/my:customer/my:accountnumber">       <xsl:copy>          <xsl:apply-templates select="@*"/>          <xsl:text>4294587576-32</xsl:text>       </xsl:copy>    </xsl:template>    <xsl:template match="/my:myfields/my:customer/my:name">       <xsl:copy>          <xsl:apply-templates select="@*"/>          <xsl:text>john smith</xsl:text>       </xsl:copy>    </xsl:template>    <xsl:template match="/my:myfields/my:customer/my:address">       <xsl:copy>          <xsl:apply-templates select="@*"/>          <xsl:text>tampa, fl  33604</xsl:text>       </xsl:copy>    </xsl:template>    <xsl:template match="/my:myfields/my:amountdue/my:amount">       <xsl:copy>          <xsl:apply-templates select="@*"/>          <xsl:text>129.85</xsl:text>       </xsl:copy>    </xsl:template>    <xsl:template match="/my:myfields/my:amountdue/my:dayspastdue">       <xsl:copy>          <xsl:apply-templates select="@*"/>          <xsl:text>54</xsl:text>       </xsl:copy>    </xsl:template> </xsl:stylesheet> 

which, when applied input sample like

<my:myfields xmlns:my="http://example.com/my">     <my:customer>         <my:name></my:name>         <my:accountnumber></my:accountnumber>         <my:address></my:address>     </my:customer>     <my:amountdue>         <my:dayspastdue></my:dayspastdue>         <my:amount></my:amount>     </my:amountdue> </my:myfields> 

outputs

<?xml version="1.0" encoding="utf-8"?><my:myfields xmlns:my="http://example.com/my">     <my:customer>         <my:name>john smith</my:name>         <my:accountnumber>4294587576-32</my:accountnumber>         <my:address>tampa, fl  33604</my:address>     </my:customer>     <my:amountdue>         <my:dayspastdue>54</my:dayspastdue>         <my:amount>129.85</my:amount>     </my:amountdue> </my:myfields> 

as said, requires xslt 2.0 , xslt 2.0 processor saxon 9 parse text file. , whoever authors text file needs make sure path expressions stylesheet maps xslt match patterns not ambiguous.
