xslt - Can't retrieve info from xml document with xsl -
i'm starting learn xml , xsl, reason can't make xpath work me in xsl. xml document structured in wrong way or why isn't price of game 14 displayed in table?
my xsl attempt pretty simple:
<?xml version="1.0" encoding="iso-8859-1"?> <!-- edited xmlspy® --> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/xsl/transform"> <xsl:template match="/"> <html> <body> <h2>my games</h2> <table border="1"> <tr bgcolor="#9acd32"> <th>game name</th> <th>price</th> </tr> <tr> <td><xsl:value-of select= "xboxspellen/spellen/spel[14]/spelnaam"/></td> <td><xsl:value-of select= "xboxspellen/spellen/spel[14]/prijs"/></td> </tr> </table> </body> </html> </xsl:template> </xsl:stylesheet> shorter version of xml code:
<?xml version="1.0" encoding="utf-8"?> <?xml-stylesheet type="text/xsl" href="xboxspellen.xsl"?> <xboxspellen xmlns="http://www.w3schools.com" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xsi:schemalocation="http://www.w3schools.com xboxspellen.xsd"> <genres> ... <genre id="adv"> <genrenaam>adventure</genrenaam> <spel idref="12"/> <spel idref="13"/> <spel idref="14"/> </genre> </genres> <spellen> ... ... <spel id="14"> <spelnaam>omerta: city of gangsters</spelnaam> <uitgever>kalypso</uitgever> <prijs>49.98</prijs> <leeftijd>16</leeftijd> <aankoop> <dag>28</dag> <maand>04</maand> <jaar>2011</jaar> </aankoop> <afbeelding>spel14.jpg</afbeelding> </spel> </spellen> </xboxspellen> i've been trying things hours don't seem find answer, if me, i'd thankful :d
you've made start. , you've bumped shins on classic slip happens sooner or later: you've written xpath expression xboxspellen/spellen/spel[14]/spelnaam , expect match element in document. elements in document not named xboxspellen, etc.: namespace-qualified, , of them have default namespace declaration (xmlns="...") in scope, full (expanded) name not xboxspellen etc., {http://www.w3schools.com}xboxspellen, {http://www.w3schools.com}spellen, etc.
correct situation making xpath expressions , xml agree on names of things. in usual case, means:
add namespace declaration xslt stylesheet, binding prefix (it doesn't matter prefix) namespace used in xml:
xmlns:w3s = "http://www.w3schools.com"
use prefix in xpath expressions:
<td><xsl:value-of select="w3s:xboxspellen /w3s:spellen /w3s:spel[14] /w3s:spelnaam" /></td> <td><xsl:value-of select="w3s:xboxspellen /w3s:spellen /w3s:spel[14] /w3s:prijs"/></td>
(i've broken lines in xpath legibility; white space legal in xpath expressions, , it's thing, too.)
now xpath expression match.
