下面是将用于转换的示例输入XML文件。需要是转换后的XML输出
<?xml version="1.0" encoding="UTF-8"?>
<catalog>
<cd xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="test1">
<title>Hide your heart</title>

<company>CBS Records</company>
<price>9.90</price>

我需要编写一个XSL转换器，这样我只能遍历具有xsi:type="test1">
的catalog/cd输出XML应该如下所示
<catalog>
<cd xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="test1">
<title>Hide your heart</title>
<artist>Bonnie Tyler</artist>
<country>UK</country>
<company>CBS Records</company>
<price>9.90</price>
<year>1988</year>
</cd>
<cd xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="test1">
<title>Still got the blues</title>
<artist>Gary Moore</artist>
<country>UK</country>
<company>Virgin records</company>
<price>10.20</price>
<year>1990</year>
</cd>
</catalog>
任何帮助都非常感谢。
欢呼请尝试以下解决方案。
XSLT遵循所谓的恒等变换模式。
