我希望使用XSLT将XML文件转换为文本文件。

我想从发布的代码中提取以下值：

老年age.patient的病人又患了另一种癌症，或者他的一个家庭患了癌症。患者来自非洲-加勒比和非洲人后裔，而非亚洲裔男性，前列腺癌是常见的。最近的研究表明肥胖和前列腺癌之间可能有联系。

    <event>
      <date key="time:timestamp" value="2018-02-04T19:16:55.290-0500"/>
      <string key="concept:name" value="history"/>
      <string key="lifecycle:transition" value="start"/>
      <string key="lifecycle:instance" value="9.1"/>
      <string key="org:resource" value="PA-014e485a-16c6-4cf5-9ade-cdf6f17c69bb"/>
      <string key="history2" value="patient in old age"/>
      <string key="history1" value="patient has another cancer or one of his family has cancer"/>
      <string key="history3" value="patient comes from African-Caribbean and African descent than in men of Asian  descen which prostate cancer is common"/>
      <string key="history4" value="obesity recent research suggests that there may be a link between obesity and prostate cancer"/>
    </event>

Answer 1

用这个：

<xsl:template match="event">
    <xsl:value-of select="descendant-or-self::string[starts-with(@key, 'history')]/@value" separator=". "/>
    <xsl:text>.</xsl:text>
</xsl:template>
