Hi All,

i'm facing a problem in parsing the following generated XLS (HTML):

<html xmlns:v="urn:schemas-microsoft-com:vml"
xmlns:o="urn:schemas-microsoft-com:office:office"
xmlns:x="urn:schemas-microsoft-com:office:excel"

<meta name="ProgId" content="Excel.Sheet"/>
<meta name="Generator" content="Microsoft Excel 10"/>
<!--[if !mso]>

</style>");
<![endif]-->

Scenario is the following:

Incoming Email in SAP System
Reading Attachment XLS (XSTRING Format)
Conversion XSTRING to STRING Table
Parse the Result(HTML Format) into Internal Table

I can't convert XSL directly because the file is in XSTRING Format and is not on Local Machine but come from third part software through email.

I want to parse the highlighted part into internal table.

What is the best approach to do this ?

Best regards,

Angelo.

Oddly enough, this reminds me of one of the most famous answers on Stack Overflow (ie. why you do NOT use regex to parse HTML)....

There are lots of possibilities. E.g., you stay with string processing and you parse the relevant part of the HTML file with the help of regular expressions. Or you treat the XSTRING directly as XML and parse it with methods of the sXML library.

Horst, thanks a lof for the help.

I'll try and search what you suggested.

Do you have any helpful example or link?

Best regards,

Angelo.

Hello,

What do you mean by "Incoming Email in SAP System" ? Where do you see, in a SAP system, an "incoming email" ? Transaction SBWP ?

former_member302911 · ‎2016 Dec 21

The transaction to see incoming e-mails is SOIN.

See this Blog

Really funny! 😄

I solved the problem parsing the file with a simple Transformation.

XML Classes return me a lot of TAG error.

I separate the relevant part from the internal table

<table border="1" cellspacing="0" cellpadding="0" width="100%">
<tr>
<th>Column 1</th>
<th>Column 2</th>
<th>Column 3</th>
</tr>
<tr>
<td style="vnd.ms-excel.numberformat:@">Text 1</td>
<td style="vnd.ms-excel.numberformat:@">Text 2</td>
<td>1</td>
</tr>
<tr>
<td style="vnd.ms-excel.numberformat:@">Text 1</td>
<td style="vnd.ms-excel.numberformat:@">Text 2</td>
<td>2</td>
</tr>
<tr>
<td style="vnd.ms-excel.numberformat:@">Text 1</td>
<td style="vnd.ms-excel.numberformat:@">Text 2</td>
<td>3</td>
</tr>
</table>

...and use this simple Transformation:

<?sap.transform simple?>
<tt:transform xmlns:tt="http://www.sap.com/transformation-templates" xmlns:ddic="http://www.sap.com/abapxml/types/dictionary" xmlns:def="http://www.sap.com/abapxml/types/defined">
  <tt:root name="READ" type="ddic:ZSTRUCTURE"/>
  <tt:template>
    <table>
      <tt:skip count="1" name="tr"/>
      <tt:loop ref=".READ">
        <tr>
          <td tt:value-ref="COL1"/>
          <td tt:value-ref="COL2"/>
          <td tt:value-ref="COL3"/>
        </tr>
      </tt:loop>
    </table>
  </tt:template>
</tt:transform>

Best regards,

Angelo.
