Detailed Description

XML tag from LDM filer.

This class allows the application to read back a custom XML section that was inserted in a LDM file header using the method SoLDMConverter::setXmlCallback().

Let's suppose the following XML text appears in the LDM file header:

   ...
   <MY_CUSTOM_TAG_SECTION>
     text
     <CUSTOM_TAG1>value1</CUSTOM_TAG1>
     <CUSTOM_TAG2>value2</CUSTOM_TAG2>
   </MY_CUSTOM_TAG_SECTION>
   ...
   

The following code will produce the output below:

   SoVolumeData* volData = new SoVolumeData(); // Volume from LDM file
   . . .
   SoVRLdmFileReader* reader = (SoVRLdmFileReader*)(volData->getReader());
   SbXmlTag myTagSection = reader->getXmlTag( "MY_CUSTOM_TAG_SECTION" );
   if (myTagSection.exist()) {
     const char* sectionName = myTagSection.getName();
     const char* sectionText = myTagSection.getText();
     for (SbXmlTag t = myTagSection.getFirstChildTag(); t.exist(); t = t.getNextSiblingTag()) {
       const char* tagName = t.getName();
       const char* tagText = t.getText();
     }
   }

Output:

   MY_CUSTOM_TAG_SECTION:text
     CUSTOM_TAG1:value1
     CUSTOM_TAG2:value2
