xslt - Add an attribute to output XML using something similar to call-template -

-

i've been searching few weeks now, , i've given up. have xslt script output xml file based on xsd definition. problem lies bit of code:

sample input, types can arbitrarily nested:

<xs:element name="rootelement">   <xs:complextype>     <xs:sequence>       <xs:element ref="r1" minoccurs="0" />       <xs:element ref="r2" minoccurs="0" />       <xs:element ref="r3" minoccurs="0">           <xs:complextype>              <xs:sequence>                  <xs:element ref="r4" minoccurs="0" />                  <xs:element ref="r5" minoccurs="0" />              </xs:sequence>           </xs:complextype>       </xs:element>     </xs:sequence>   </xs:complextype> </xs:element>

xsl: 

    <!-- wish work -->     <xsl:if test="$minoccurs">         <xsl:attribute name="minoccurs"><xsl:value-of select="$minoccurs"/></xsl:attribute>     </xsl:if>      <xsl:choose>         <xsl:when test="@ref">             <xsl:variable name="elementref" select="current()/@ref"/>             <xsl:for-each select="//xs:element[@name=$elementref]">                     <xsl:call-template name="element">                         <xsl:with-param name="minoccurs" select="./@minoccurs"/>                     </xsl:call-template>             </xsl:for-each>         </xsl:when>         <!-- abridged -->     </xsl:choose> </xsl:template>

output like:

<rootelement>     <r1 minoccurs="0" />     <r2 minoccurs="0" />     <r3 minoccurs="0">         <r4/>         <r5/>     </r3> </rootelement>

i'm doing recursive call , works fine. but, can't add attribute, , i've read online. how can change able add attribute?

given xml input,

<?xml version="1.0" encoding="utf-8"?> <xs:schema xmlns:xs="http://www.w3.org/2001/xmlschema" elementformdefault="qualified">   <xs:element name="rootelement">     <xs:complextype>       <xs:sequence>         <!-- replaced original @ref @name -->         <xs:element name="r1" minoccurs="0" />         <xs:element name="r2" minoccurs="0" />         <xs:element name="r3" minoccurs="0">           <xs:complextype>             <xs:sequence>               <xs:element name="r4" minoccurs="0" />               <xs:element name="r5" minoccurs="0" />             </xs:sequence>           </xs:complextype>         </xs:element>       </xs:sequence>     </xs:complextype>   </xs:element> </xs:schema>

the following xslt,

<?xml version="1.0" encoding="iso-8859-1"?> <xsl:stylesheet version="1.0"                 xmlns:xs="http://www.w3.org/2001/xmlschema"                 xmlns:xsl="http://www.w3.org/1999/xsl/transform">   <xsl:output method="xml" indent="yes"/>   <xsl:strip-space elements="*"/>    <xsl:template match="xs:element">     <xsl:element name="{@name}">       <xsl:if test="@minoccurs">         <xsl:attribute name="minoccurs">           <xsl:value-of select="@minoccurs"/>         </xsl:attribute>       </xsl:if>       <xsl:apply-templates/>     </xsl:element>   </xsl:template> </xsl:stylesheet>

will produce following xml output,

<?xml version="1.0" encoding="utf-8"?> <rootelement>    <r1 minoccurs="0"/>    <r2 minoccurs="0"/>    <r3 minoccurs="0">       <r4 minoccurs="0"/>       <r5 minoccurs="0"/>    </r3> </rootelement>

as requested.

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

php - Best Light server (Linux + Web server + Database) for Raspberry Pi -

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
