Detailed Description

VM opcode snippet for retrieving the concatenated text of an XML node.

Included by vm.c; implements OP_XML_TEXT.

Opcode: OP_XML_TEXT

• Stack effect: pop (int node_handle) → push (string text)
• Behavior: Retrieves the node's textual content as produced by xmlNodeGetContent(), which concatenates all descendant text nodes. If the node is invalid or has no textual content, an empty string is pushed.
• Gating: If FUN_WITH_XML2 is disabled, the input is discarded and an empty string is pushed.

Notes

• The returned string is copied into a VM string value; libxml2 buffers are freed immediately after use.

Example // stack: [ node_handle ] OP_XML_TEXT // → [ "Hello world" ]
