Subject: [xsl] Reordering a complex hierarchical structure From: Ian Wootten <I.M.Wootten@xxxxxxxxxxxxxxxx> Date: Wed, 30 Aug 2006 16:10:33 +0100 |
I'm attempting to structure a complex xml structure to be represented in a more meaningful manner. I'm doing this within a xml transformer in Java.
<session> <service> <name>somename</name> <id>1</id> </service> <metric name="somemetric">value1</metric> <metric name="anothermetric">value2</metric> <metric name="andanothermetric">value3</metric> </session> <session> <service> <name>somename</name> <id>1</id> </service> <metric name="somemetric">value4</metric> <metric name="anothermetric">value5</metric> <metric name="andanothermetric">value6</metric> </session> <session> <service> <name>anothername</name> <id>2</id> </service> <metric name="somemetric">value7</metric> <metric name="anothermetric">value8</metric> <metric name="andanothermetric">value9</metric> </session> <session> <service> <name>anothername</name> <id>2</id> </service> <metric name="somemetric">value10</metric> <metric name="anothermetric">value11</metric> <metric name="andanothermetric">value12</metric> </session>
service ----> id1 ----> somemetric ----> value1 -----> somemetric ----> value4 ----> anothermetric ----> value2 -----> anothermetric ----> value5 -----> andanothermetric ----> value3 -----> andanothermetric ----> value6 ------> id 2 ----> somemetric----> value7 -----> somemetric ----> value10 ----> anothermetric ----> value8 -----> anothermetric ----> value11 -----> andanothermetric ----> value9 -----> andanothermetric ----> value12
I currently use an xsl stylesheet like the following, which basically collects all the metrics from the document and orders them by the name they have.
<xsl:template match="/"> <interactions> <xsl:apply-templates select="//session"/> </interactions> </xsl:template>
<xsl:template match="session"> <service name="{service/name}"> <request><xsl:value-of select="service/id" /></request> <xsl:apply-templates select="metric[generate-id(.) = generate-id(key('x', @name)[1])]" /> </service> </xsl:template>
<xsl:template match="metric"> <metric name="{@name}"> <xsl:for-each select="key('x', @name)"> <xsl:for-each select="value"> <value> <xsl:value-of select="node()" /> </value> </xsl:for-each>
</xsl:for-each> </metric> </xsl:template>
I am struggling to determine how I can "divide" this structure up so it appears by the identifier on each service. Once the structure has been created in this manner the identifiers for the services which they were under are lost. Is anyone able to help?
