XSL 中使用一組不固定資料來判斷另一組資料的輸出值
XML 如下
<?xml version='1.0'?>
<?xml-stylesheet type="text/xsl" href="key_sample.xsl" ?>
</document>
<test id="1" name="a">
<test id="2" name="b">
<test id="3" name="c">
<test id="4" name="d">
輸出結果如下
id=1 value=value1 test name=a
id=2 value=value2 test name=a
id=3 value=value3 test name=c
id=4 value=value4 test name=b
<?xml version='1.0'?>
<?xml-stylesheet type="text/xsl" href="key_sample.xsl" ?>
</document>
<test id="1" name="a">
<test id="2" name="b">
<test id="3" name="c">
<test id="4" name="d">
<data>
<item>
<id>1</id>
<value>value1</value>
<testid>1</testid>
</item>
<item>
<id>2</id>
<value>value2</value>
<testid>1</testid>
</item>
