Hi,

1. read the xml into a string

2. convert the string to xstring using SCMS_STRING_TO_XSTRING

3. now use FM SMUM_XML_PARSE and pass the xstring xml_input parameter of that function.

this will parse the whole xml and give you an itab of element name value pairs which you can read easily

Also check this

Uwe has nice code there ...

Regards,

Karol

Rajendra,

For this you need to write XSLT program to convert from XML to internal table.

Here are some tips to do so.

1. Write XSLT program. T.code XSLT . e.g. XSLT name "ZTRANS".

2. Write ABAP program

Which includes declaration of internal tables

that you need "IT_DATA".

Upload XML data to an internal table "IT_XML "

use below statement to convert XML to internal table.

Call transformation ZTRANS

source XML IT_XML

result IT_DATA.

Follow below link for SAP example for the same.

[http://help.sap.com/saphelp_nw70/helpdata/en/a4/1f1e400191f72ee10000000a1550b0/content.htm]

I worked on serialization of data side(internal table data to XML ).

Thanks,

Amara.

Hi Rajender,

I've written a tutorial that can help you I believe:

http://www.heidoc.net/joomla/technology-science/sap-and-xslt/5-tutorial-data-exchange-between-abap-and-xml

(It contains an example with complete source code)

Best wishes,

hi~I am facing a problem with xslt transaction.

the following are the codes in ABAP program:

WA_SOURCE-NAME = 'D2CXML'.

GET REFERENCE OF T_FINAL_XML INTO WA_SOURCE-VALUE.

APPEND WA_SOURCE TO T_SOURCE.

CLEAR G_XML_STRING.

CALL TRANSFORMATION ZFIGL4

SOURCE (T_SOURCE)

RESULT XML G_XML_STRING.

IF SY-SUBRC <> 0.

ELSE.

G_XML_STRING1 = G_XML_STRING.

REPLACE 'utf-16' WITH 'utf-8' INTO G_XML_STRING.

ENDIF.

the following are the codes in XSLT transaction ZFIGL4:

<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">

<!~~xsl:output encoding="utf-8" indent="yes"/~~>

<xsl:template match="D2CXML">

<voucher_id>

<xsl:apply-templates/>

</voucher_id>

</xsl:template>

<xsl:template match="item">

<voucher_head>

<xsl:attribute name="no">

<xsl:value-of select="AC_DOC_NO"/>

</xsl:attribute>

<xsl:apply-templates select="COMP_CODE"/>

</company>

<voucher_type>

<xsl:apply-templates select="AC_DOC_TYP"/>

</voucher_type>

<fiscal_year>

<xsl:apply-templates select="GJAHR"/>

</fiscal_year>

<accounting_period>

<xsl:apply-templates select="MONAT"/>

</accounting_period>

<voucher_id>

<xsl:apply-templates select="AC_DOC_NO"/>

</voucher_id>

<xsl:apply-templates select="PSTNG_DATE"/>

</prepareddate>

<xsl:apply-templates select="X-MLSTRUCT"/>

</voucher_head>

</xsl:template>

<xsl:template match="X-MLSTRUCT">

<xsl:apply-templates/>

</xsl:template>

<xsl:template match="item/X-MLSTRUCT">

<entry>

<entry_id>

<xsl:apply-templates select="ITEM_NUM"/>

</entry_id>

<account_code>

<xsl:apply-templates select="GL_ACCOUNT"/>

</account_code>

<xsl:apply-templates select="POSTXT"/>

</abstract>

<primary_debit_amount>

<xsl:apply-templates select="DEBIT_DC"/>

</primary_debit_amount>

<natural_debit_currency>

<xsl:apply-templates select="DEBIT_DC"/>

</natural_debit_currency>

<primary_credit_amount>

<xsl:apply-templates select="CREDIT_LC"/>

</primary_credit_amount>

</entry>

</xsl:template>

</xsl:transform>

But the result shows in XML file as this :

<?xml version="1.0" encoding="utf-8" ?>

<voucher_id />

No data in the internel table is output at all .DId i miss anything ?
