Large XML Files and FOP: Out of Memory Exception

hi all,

i'm trying to use large xml file to create  a tabel in pdf format. the
xml contains about 40'000 nodes:

	<item>
		<Field name="Viw#">abaqq</Field>
		<Field name="Entfld#">8zcyx</Field>
		<Field name="Sequence">10</Field>
		<Field name="Dgn#"/>
		<Field name="Val#validate"/>
		<Field name="Systemhidden">N</Field>
		<Field name="Prefix"/>
		<Field name="entfldFldName">Rulobj#</Field>
		<Field name="entfldFldImplname">RULOBJITMRULOBJ#</Field>
		<Field name="entfldRelpth#"/>
		<Field name="entfldMandatory">Y</Field>
		<Field name="entfldFldIschangecounter">N</Field>
		<Field name="entfldFldIsdatapoolid">N</Field>
		<Field name="entfldFldChgcnt">33</Field>
		<Field name="entfldFldCategory">2</Field>
		<Field name="entfldFldFld#domain">8zfnz</Field>
		<Field name="entfldFldJavabasictype"/>
		<Field name="entfldFldJavadomclass"/>
		<Field name="entfldFldSqlbasictype">VARCHAR2</Field>
		<Field name="entfldFldPrecision"/>
		<Field name="entfldFldLength"/>
		<Field name="entfldFldEnumerated">N</Field>
		<Field name="entfldFldFreefieldlangdep">N</Field>
		<Field name="entfldFldVal#validate"/>
		<Field name="entfldDbr#"/>
		<Field name="entfldSubtype">N</Field>
		<Field name="entfldChgcnt">2</Field>
		<Field name="entfldEnt#">8zcyh</Field>
		<Field name="entfldFld#">8zcyv</Field>
		<Field name="entfldForeignkey">Y</Field>
		<Field name="entfldPrimarykey">N</Field>
		<Field name="entfldNaturalkey">Y</Field>
		<Field name="viwBasviw#">abaqo</Field>
		<Field name="viwType">S</Field>
		<Field name="entfldFldFlagsmartdefault">0</Field>
		<Field name="entfldFldPrompttype"/>
		<Field name="entfldFldBasviw#foreignkeynk"/>
		<Field name="#">abaqz</Field>
		<Field name="Chgcnt">0</Field>
	</item>

Here's our gathered knowledge about handling big files:
http://xml.apache.org/fop/running.html#memory

I'm certain you'll find your answers there. If not, try searching the
mailing list archives and ask again if you are still not successful
after that.

I hope that helps.
