如何通过 abap 中的 XSLT 程序读取 XML 文件的属性

how to read attributes of XML file via XSLT program in abap

我有一个如下所示的 XML 文件,我需要读取属性值并将其提取到内部 table。

但未获取值,内部 table 仍为空。如果代码有任何问题,请告诉我。提前致谢!

XML 文件:

 <?xml version="1.0" encoding="iso-8859-1" ?>
    <CUSTOMERS>
      <PERSON customer_id="1" first_name="Jan" last_name="krohn">
      </PERSON>
      <PERSON customer_id="2" first_name="Jan1" last_name="krohn1">
      </PERSON>
    </CUSTOMERS>

xslt 程序:

<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
 <xsl:output encoding="iso-8859-1" indent="yes" method="xml" version="1.0"/>
 <xsl:strip-space elements="*"/>
 <xsl:template match="/">
 <asx:abap xmlns:asx="http://www.sap.com/abapxml" version="1.0">
 <asx:values>
 <IPERSON>
 <xsl:for-each select="/CUSTOMERS/PERSON">
 <item>
 <CUST_ID>
 <xsl:value-of select="@customer_id"/>
 </CUST_ID>
 <FIRSTNAME>
 <xsl:value-of select="first_name"/>
 </FIRSTNAME>
 <LASTNAME>
 <xsl:value-of select="last_name"/>
 </LASTNAME>
 </item>
 </xsl:for-each>
 </IPERSON></asx:values>
 </asx:abap>
 </xsl:template>
</xsl:transform>

abap 调用:

TYPES: BEGIN OF ts_person,
 cust_id(4) TYPE c,
 firstname(20) TYPE c,
 lastname(20) TYPE c,
* ONE_STRING TYPE CHAR50,
 END OF ts_person.

DATA : it_data TYPE STANDARD TABLE OF ts_person,
 wa_data TYPE ts_person.

DATA: gt_result_xml TYPE abap_trans_resbind_tab,
 gs_result_xml TYPE abap_trans_resbind.

GET REFERENCE OF it_data INTO gs_result_xml-value.
gs_result_xml-name = 'IPERSON'.
APPEND gs_result_xml TO gt_result_xml.

CALL TRANSFORMATION ZXSLT_1   " xslt file above
SOURCE XML it_xml
RESULT (gt_result_xml).

您缺少 @ 属性名称的符号 first_namelast_name

<xsl:for-each select="/CUSTOMERS/PERSON">
  <item>
    <CUST_ID>
      <xsl:value-of select="@customer_id" />
    </CUST_ID>
    <FIRSTNAME>
      <xsl:value-of select="@first_name" />
    </FIRSTNAME>
    <LASTNAME>
      <xsl:value-of select="@last_name" />
    </LASTNAME>
  </item>
</xsl:for-each>
