I wanted to process a 161mo database, but java saxon9he run out of memory at 300mb of ram and the .NET at 1700mb ram, so I need to use streaming, so I use XMLSpy demo, but I still don't understand the xpath expressions child parent logic. I am on windows xp sp3 32bit 4gb of ram.
<xsl:iterate select="db_entry">
<xsl:apply-templates select="db_entry"/>
</xsl:iterate>
What the correct way to stream this with xsl:iterate or maybe xsl:for-each is sufficiente ? There is nearly 60000 entries in this database. I mean how to correctly write this because a db_entry within a db_entry does not work.
EDIT:
<xsl:template match="databank_export">
<xsl:iterate select="db_entry">
<xsl:apply-templates select="public_data"/>
<xsl:text> |</xsl:text>
<xsl:apply-templates select="text_data"/>
<xsl:text> |</xsl:text>
<xsl:apply-templates select="research_data"/>
<xsl:text> </xsl:text>
</xsl:iterate>
</xsl:template>
I replace the db_entry xsl:template by xsl:iterate but then XMLspy can't load the big file so it appears that streaming doesn't work. Am I doing it right or is it program limitations or demo limitations ?
2nd EDIT: I'll put here my entire xsl code:

It work with a small sample file but not with the whole 161mb file.
Best regards.
