ABAP/SAP 中 XSLT 的特殊特性？

[英]Special characteristics for XSLT in ABAP/SAP?

问题描述

我正在尝试使用 XSLT 将传入的 XML 文件解析为 SAP 结构。 我阅读了很多关于它的教程并尝试了很多方法来让它工作，但有些不太合适。

我的输入 XML（缩短的例子）：

此 XML 文件似乎没有任何与之关联的样式信息。 文档树如下所示。

                    </xsl:if>

                </CUSTOMVARIABLES>
                <RESULT>  <xsl:value-of select="result"/> </RESULT>
                <MESSAGE> <xsl:value-of select="message"/> </MESSAGE>
              </VISIT>
            </xsl:for-each>
          </RESULT>
        </asx:values>
      </asx:abap>
    </xsl:template>
    </xsl:transform>

另外，万一重要，我的转换调用：

 CALL TRANSFORMATION zz_tf_xmlvisit
      SOURCE XML myXml
      RESULT result = myVisits.

现在的问题是：一旦解析器移动到第二个 for-each 循环中的第一个元素（在本例中为“type”），它就会崩溃并且调试器会抛出一个 CX_XSLT_FORMAT_ERROR。 没有调试它只是说“XML-ABAP 转换的意外文本”。

我强烈认为 XSLT 解析器存在一些我不知道的特定于 SAP 的问题。 如果我使用在线验证器验证我的转换，它就可以正常工作。

知道了：

...
 <DEVICETYPE>            <xsl:value-of select="deviceType"/>           </DEVICETYPE>
            <ACTIONDETAILS>
            <xsl:for-each select="actionDetails/row">
<!--              <xsl:variable name="row" select="current()" />-->
              <ACTIONDETAIL>
                <TYPE>              <xsl:value-of select="type"/>               </TYPE>
                <URL>               <xsl:value-of select="url"/>                </URL>
                <GOALNAME>          <xsl:value-of select="goalName"/>           </GOALNAME>
                <GOALID>            <xsl:value-of select="goalId"/>             </GOALID>
                <SITESEARCHKEYWORD> <xsl:value-of select="siteSearchKeyword"/>  </SITESEARCHKEYWORD>
                <ITEMS>             <xsl:value-of select="items"/>              </ITEMS>
                <ITEMDETAILS>
                <xsl:for-each select="itemDetails/row">
                  <ITEMDETAIL>
                    <ITEMSKU>       <xsl:value-of select="itemSKU"/></ITEMSKU>
                    <ITEMNAME>      <xsl:value-of select="itemName"/></ITEMNAME>
                    <ITEMCATEGORY>  <xsl:value-of select="itemCategory"/></ITEMCATEGORY>
                    <PRICE>         <xsl:value-of select="price"/></PRICE>
                    <QUANTITY>      <xsl:value-of select="quantity"/></QUANTITY>
                  </ITEMDETAIL>
                </xsl:for-each>
                </ITEMDETAILS>
              </ACTIONDETAIL>
            </xsl:for-each>
            </ACTIONDETAILS>
...

我的结构确实是正确的：P
我忘记为我的 ACTIONDETAIL 集合添加父节点 ACTIONDETAIL S。 这就是为什么它毕竟在错误的节点中......我没有解释为什么它在验证器中正常工作，但至少它现在正在工作。 谢谢！
