这是从Attaching ancestor attributes to child nodes
链接的我从大型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

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"

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>
