Problem in parsing white spaces using if_ixml_parser

[Former Member]

Hello People,

I have a problem in parsing XML file in one of my programs.

The program uses the method get_value( ) of class if_ixml_node to fetch a value. In the XML file when the value is spaceA, then after parsing, the value fetched is A and not spaceA.

Is there any way to fetch the white spaces also?

Here is the sample tag. The value inside the tags is " A" and after parsing I get "A" the blank is ignored.

<ns1:IndiceCible> A</ns1:IndiceCible>

DATA : l_node_fils TYPE REF TO if_ixml_node.

indice_val = l_node_fils->get_value( ).

In some XML parsing forums I saw that if we add the option as shown below, then the parsing works properly. But this did not work in my case.

<ns1:IndiceCible xml:space="preserve"> A</ns1:IndiceCible>

The input XML file is as follows.

<?xml version="1.0" encoding="UTF-8"?><SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"><SOAP-ENV:Header><env:Flow xmlns:env="http://xml.inetpsa.com/Structure/Informatique/DeveloppementSI/ReferentielEchange"><env:MessageID>0414
