如何使用xslt删除XML节点值中的前导零

<xsl:template match="number">
  <!-- 在这里添加代码来删除前导零 -->
</xsl:template>

<xsl:template match="number">
  <xsl:value-of select="substring(string(.), number(string(.)) != 0)" />
</xsl:template>

import javax.xml.transform.*;
import javax.xml.transform.stream.*;

public class XSLTExample {
  public static void main(String[] args) throws Exception {
    TransformerFactory factory = TransformerFactory.newInstance();
    Source xslt = new StreamSource(new File("remove-leading-zeros.xsl"));
    Transformer transformer = factory.newTransformer(xslt);
    Source xml = new StreamSource(new File("input.xml"));
    transformer.transform(xml, new StreamResult(new File("output.xml")));
  }
}
