XML XSLT使用auto gen PK和FK帮助父级子级

标签： xml xslt

我有一个XML结构，其中包含组织层次结构，但没有任何关系，或者＆＃39;键＆＃39;定义

这是我的xml

＆＃13;
＆＃13; 
data.filter(x=>x.cat_type == _archid)
＆＃13;
＆＃13;
＆＃13;

我需要一个能产生以下输出的XSLT

＆＃13;
＆＃13;

  </entity>
  </webreports>
＆＃13;
＆＃13;
＆＃13;

所以基本上我需要将每个子键和子column_metadata元素与父实体

相关联

任何和所有帮助表示赞赏！

我试过这个......

这两个模板会不会这样做...... 

<xsl:template match="column_metadata">
  <xsl:copy>
    <xsl:apply-templates select="@*"/>
    <col_metadata_entityKEY>
      <xsl:value-of select="ancestor::entity/entity_name" />
    </col_metadata_entityKEY>
    <xsl:apply-templates />
  </xsl:copy>
</xsl:template>

<xsl:template match="key">
  <xsl:copy>
    <xsl:apply-templates select="@*"/>
    <col_name_entityKEY>
      <xsl:value-of select="ancestor::entity/entity_name" />
    </col_name_entityKEY>
    <xsl:apply-templates />
  </xsl:copy>
</xsl:template>

或许你可以将它们组合成一个...... 

<xsl:template match="key|column_metadata">
  <xsl:copy>
    <xsl:apply-templates select="@*"/>
    <xsl:element name="{if (local-name() = 'key') then 'col_name' else 'col_metadata'}_entityKEY">
      <xsl:value-of select="ancestor::entity/entity_name" />
    </xsl:element>
    <xsl:apply-templates />
  </xsl:copy>
</xsl:template>
