All of a sudden I get a crash in my app trying to read a path from an XML file. The crash comes from the function TDOMNamedNodeMap.Find that crashes on this line:

C := TDOMNode(FList.List^[I]).CompareName(name);

The strange thing is that a simplified example app does not crash! In any case I'm 100% sure the path exists and either way even if it didn't XMLConfig should not crash. The message form the lazarus code inspector is: Type TDOMNODE has no component named COMPARENAME.The code also never reaches the CompareName function when I set a breakpoint.

I'm at a loss. Is any one capable to understand what is happening?

Rgds, Darius

My code is:

    c := cache.GetValue('filelist/item_1/crc', 0);

The XML is:

<?xml version="1.0" encoding="utf-8"?>
<CONFIG>
<filelist type="filecache" count="1">
<item_1 crc="30150" filename="C:\myfile.txt"/>
</filelist>
</CONFIG>

The BT is:

Hi, I can only say that TDOMNode from Laz2_DOM in trunk has function CompareName.

The second TDOMNode from unit DOM (fcl-xml) has that function too, in FPC 3.0.4. V.

Hi, I can only say that TDOMNode from Laz2_DOM in trunk has function CompareName.

I'm using FPC 3.0.4 indeed. No dependency to the LCL.

Hmm, I remember there are two ways how to work with XML: Laz2_xxx and fcl-xml. My idea was that you got some wrong TDOMNode in the path. V.

Laz2_DOM is in LazUtils, not in the LCL.
