XSLT grouping every 4 adjacent elements -

-

i have xml below.

source xml:

<?xml version="1.0" encoding="windows-1252"?> <xml>   <attributes>     <attribute>       <name>collection</name>       <value />     </attribute>     <attribute>       <name>a</name>       <value>testing</value>     </attribute>     <attribute>       <name>b</name>       <value>blank</value>     </attribute>     <attribute>       <name>c</name>       <value>11</value>     </attribute>     <attribute>       <name>d</name>       <value>na</value>     </attribute>     <attribute>       <name>a</name>       <value>testing1</value>     </attribute>     <attribute>       <name>b</name>       <value>red</value>     </attribute>     <attribute>       <name>c</name>       <value>12</value>     </attribute>     <attribute>       <name>d</name>       <value>nat</value>     </attribute>   </attributes> </xml>

from above xml how can this. want group them in groups of 4. first 4 (in source xml) element /attribute/name='a' - /attribute/name='d' in first group. , next 4 /attribute/name='a' - /attribute/name='d' in second group .... below

thanks in advance

output

 <collection name="collection" >            <complexattr>                   <attr name="a" value="testing" />                   <attr name="b" value="blank" />                   <attr name="c" value="11" />                   <attr name="d" value="na" />            </complexattr>            <complexattr >                   <attr name="a" value="testing1" />                   <attr name="b" value="red" />                   <attr name="c" value="12" />                   <attr name="d" value="na" />            </complexattr>     </collection>

this faq. see link in comments question. here stylesheet tailored input , desired output:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/xsl/transform">     <!--  number of items include in each group -->     <xsl:variable name="group" select="4" />     <xsl:template match="/">         <collection name="collection">             <xsl:apply-templates                 select="xml/attributes/attribute[not(name='collection')]                                                 [position() mod $group = 1]" />         </collection>     </xsl:template>     <xsl:template match="attribute" mode="inner">         <attr name="{name}" value="{value}" />     </xsl:template>     <xsl:template match="attribute">         <complexattr>             <xsl:apply-templates                 select=".|following-sibling::attribute[position() &lt; $group]"                 mode="inner" />         </complexattr>     </xsl:template> </xsl:stylesheet>

produces:

<collection name="collection">     <complexattr>         <attr name="a" value="testing" />         <attr name="b" value="blank" />         <attr name="c" value="11" />         <attr name="d" value="na" />     </complexattr>     <complexattr>         <attr name="a" value="testing1" />         <attr name="b" value="red" />         <attr name="c" value="12" />         <attr name="d" value="nat" />     </complexattr> </collection>

php - What is the difference between $_SERVER['PATH_INFO'] and $_SERVER['ORIG_PATH_INFO']? -

-
what’s difference between $_server['path_info'] , $_server['orig_path_info'] ? how use them? when run print_r($_server) , path_info , orig_path_info not present in array. why not? how can enable them? i have read php manual on them, still don’t understand them. the path_info variable present if invoke php script this: http://www.example.com/phpinfo.php/hello_there it's /hello_there part after .php script. if don't invoke url that, there won't $_server["path_info"] environment variable. the porig_ prefix uncommon. path_info standard cgi-environment variable, , should never prefixed. did read that? (there issues around php3/php4 if invoked php interpreter via cgi-bin/ - hardly has such setups today.) for reference: http://www.ietf.org/rfc/rfc3875

i'm attempting recode old c++ program in fortran make use of lapack (i'm aware c++ have lapack++, i'm having lot of trouble installing it, gave up). i didn't have problems compilation, when had variables declared real . when started coding section of program required lapack, found parameters passed dsyev need double precision . tried change double precision (including changing hard coded numbers double precision counterparts, i.e. 0.0 -> 0.0d0) when try compile, following error of functions , subroutines i've written: error: return type mismatch of function <function> @ (1) (real(4)/real(8)) i'm not sure coming from, in program has been changed double precision. for example, i've declared following: double precision :: alpha(3),d(3),zeta1,zeta2 double precision :: a1(3),a2(3),d1(3),d2(3) double precision :: pi pi = 3.14159265359d0 alpha = (/0.109818d0, 0.405771d0, 2.22766d0/) d = (/0.444635d0, 0.535328d0, 0.154329d0 /) 10 i=1,3 ...

queue - mq_receive: message too long -

-
i implementing communication between 2 processes using queue. problem when call function mq_receive, error: message long. i have done following: struct mq_attr attr; long size = attr.mq_msgsize; .... // initializing queue "/gateway" int rc = mq_receive(gateway, buffer, size, &prio); if print size value, size=1, while when print same size program (got same mechanism), not long integer ( -1217186280 )... how can solve error?....so while size = 1, believe it's right "message long" why 1? p.s. have tried put : int rc = mq_receive(gateway, buffer, sizeof(buffer), &prio); but no result. it seems need read docs more carefully. when call mq_receive should pass size of destination buffer. this size must greater mq_msgsize attribute of queue . in addition, seems have error in queue attributes initialisation makes proper mq_receive call impossible. here standard message queue session: fill mq_attr struct ( doc ): struct mq_a...
