xml - Normalize whitespace in mixed-content elements, in XSLT 1.0 -


[edit: changed title better conceptualize question.]

the value of attribute @xml:space can either "default" or "preserve". xml specifies second means leaves first application. (i think have correct.) if application wants default implement xschema's collapse? how xslt 1.0 this?

i think built-in template processing text, is,

<xsl:template match="text()"> <xsl:value-of select="."/> </xsl:template>

would need replaced pseudo-code:

<xsl:choose> <xsl:when test="../@xml:space='preserve'" <xsl:value-of select="."/> </xsl:when> <xsl:otherwise> if position(.)=1 output ltrim(value-of(.)) if position(.)=last() output rtrim(value-of(.)) if position(.)= 1 , last()=1 output normalize-space(.) </xsl:otherwise> </xsl:choose>

this input then:

<persname> man <forename>edward</forename> <forename>george</forename> <surname type="linked">bulwer-lytton</surname>, <rolename>baron lytton of <placename>knebworth</placename> </rolename> </persname>

would rendered correctly the man edward george bulwer-lytton, baron lytton of knebworth space before the man , after knebworth trimmed , spaces between edward , george collapsed. (the example tei.)

[edit: removed incorrect , misleading paragraph here.]

the xslt 1.0 implement pseudo-code need executed every text node. wouldn't ugly , slow? [edit: or maybe not. simplified pseudo code. there fast trim routines? choose slow?]

bottom line: how 1 implement xschema's collapse in xslt 1.0 (with browser-embedded extensions)?

i hope i'm saying correctly. , hope code simple. haven't yet seen how can be. [edit: changed xs:collapse xschema's collapse.]

here close want ...

<?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/xsl/transform"> <xsl:output method="text" indent="yes"/> <xsl:strip-space elements="*"/> <xsl:template match="/"> demonstration of collapsed white space. ======================================= <xsl:apply-templates select="*"/> </xsl:template> <xsl:template match="text()"> <xsl:value-of select="concat(normalize-space(.),' ')" /> </xsl:template> </xsl:stylesheet>

this produces output ...

demonstration of collapsed white space. ======================================= man edward george bulwer-lytton , baron lytton of knebworth

php - Get uncommon values from two or more arrays -

is there function in php give array of uncommon values 2 or more arrays? for example: $array1 = array( "green", "red", "blue"); $array2 = array( "green", "yellow", "red"); .... $result = function_needed($array1, $array2,...); print_r($result); should give output: array("blue", "yellow", ...); use array_diff , array_merge : $result = array_merge(array_diff($array1, $array2), array_diff($array2, $array1)); here's demo. for multiple arrays, combine callback , array_reduce : function unique(&$a, $b) { return $a ? array_merge(array_diff($a, $b), array_diff($b, $a)) : $b; } $arrays = array( array('green', 'red', 'blue'), array('green', 'yellow', 'red') ); $result = array_reduce($arrays, 'unique'); and here's demo of that.

Adding duplicate array rows in Php -

i create function in php adds rows of array shared column value. so input. $test = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); and output. $testduplicatefree = array( array("c", 7, 9), array("test", 5, 6) ) ); i'm thinking function combine_duplicates($array,$col){ ... ... return $duplicatefreearray; } where $col duplicate free array. so, in case, combine_duplicates($test,0); would me desired output. this. <?php function combine_duplicates($array,$col) { $index = array(); foreach ($array $row) { $key = $row[$col]; if (!isset($index[$key])) { $index[$key] = $row; } else { ($i = 0; $i < count($row); ++$i) { if ($i != $col) { $index[$key][$i] += $row[$i]; } } } } return array_values($index); } $array = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); print_r(combine_duplicates($array, 0)); try here: http://codepad.org/mdhesqhi
