我从大型xml数据集中提取名称，我需要提取displayname和其他名称类型（目前我只选择同义词和SystematicNames）。现在，在我到目前为止已经得到了一个很棒的人的帮助下，但它只提取了每种类型的第一个......

示例XML 

  <Chemical id="0000103902" displayFormula="C8-H9-N-O2" displayName="Acetaminophen [USP:JAN]">
    <NameList>
      <DescriptorName>Acetaminophen<SourceList><Source>MeSH</Source></SourceList></DescriptorName>
      <NameOfSubstance>Acetaminophen<SourceList><Source>HSDB</Source><Source>MeSH</Source></SourceList></NameOfSubstance>
      <NameOfSubstance>Acetaminophen [USP:JAN]<SourceList><Source>NLM</Source></SourceList></NameOfSubstance>
      <MixtureName>Actifed Plus<SourceList><Source>MeSH</Source></SourceList></MixtureName>
      <MixtureName>Jin Gang<SourceList><Source>NLM</Source></SourceList></MixtureName>
      <MixtureName>Talacen<SourceList><Source>NLM</Source></SourceList></MixtureName>
      <SystematicName>Acetamide, N-(4-hydroxyphenyl)-<SourceList><Source>EPA SRS</Source><Source>MeSH</Source><Source>TSCAINV</Source></SourceList></SystematicName>
      <SystematicName>Acetaminophen<SourceList><Source>CCRIS</Source></SourceList></SystematicName>

      <SystematicName>Paracetamol<SourceList><Source>ECHA</Source><Source>EINECS</Source></SourceList></SystematicName>
      <Synonyms>4-13-00-01091 (Beilstein Handbook Reference)<SourceList><Source>RTECS</Source></SourceList></Synonyms>
      <Synonyms>Abensanil<SourceList><Source>HSDB</Source><Source>RTECS</Source></SourceList></Synonyms>

      <Synonyms>Acetamide, N-(p-hydroxyphenyl)-<SourceList><Source>RTECS</Source></SourceList></Synonyms>
    </NameList>
  </Chemical>

然而，这仅给出： - 

"Acetaminophen [USP:JAN]","https://chem.nlm.nih.gov/chemidplus/sid/startswith/0000103902","nlm"
"Acetamide, N-(4-hydroxyphenyl)-","https://chem.nlm.nih.gov/chemidplus/sid/startswith/0000103902","nlm"
"4-13-00-01091 (Beilstein Handbook Reference)","https://chem.nlm.nih.gov/chemidplus/sid/startswith/0000103902","nlm"

如何以同样的方式提取所有孩子？

答案 0 :(得分：0)

通过为这些元素添加<SystematicName>循环，可以在<Synonyms>和<xsl:for-each>节点中打印文本值。 <xsl:if>条件也可以在<xsl:for-each>选择中处理。

请修改<xsl:template match="/">，如下所示。

<xsl:template match="Chemical[@displayName != '' and @displayName != 'INDEX NAME NOT YET ASSIGNED']">
    <xsl:variable name="idValue" select="@id" />
    <xsl:call-template name="printValues">
        <xsl:with-param name="val1" select="$idValue" />
        <xsl:with-param name="val2" select="@displayName" />
    </xsl:call-template>
    <xsl:for-each select="NameList/SystematicName[text() != '']">
        <xsl:call-template name="printValues">
            <xsl:with-param name="val1" select="$idValue" />
            <xsl:with-param name="val2" select="normalize-space(text())" />
        </xsl:call-template>
    </xsl:for-each>
    <xsl:for-each select="NameList/Synonyms[text() != '']">
        <xsl:call-template name="printValues">
            <xsl:with-param name="val1" select="$idValue" />
            <xsl:with-param name="val2" select="normalize-space(text())" />
        </xsl:call-template>
    </xsl:for-each>
</xsl:template>
