Hi,

i'm currently porting gazpacho (a wysiwyg gtk ui file editor) to lxml, unfortunately the pretty printer prints with an indent of 2 and in order to match the convention i need an indent of 4

is there any simple way to archive pretty dumping to a file with an indent of 4?

You could adapt the following XSL Transformation: prettyXSL = """<?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output encoding="UTF-8" method="xml"/> <xsl:param name="indent-increment" select="' '"/> <xsl:template match="* | comment()|processing-instruction()"> <xsl:param name="indent" select="' '"/> <xsl:value-of select="$indent"/> <xsl:copy> <xsl:copy-of select="@*"/> <xsl:apply-templates> <xsl:with-param name="indent" select="concat($indent, $indent-increment)"/> </xsl:apply-templates> <xsl:if test="*"> <xsl:value-of select="$indent"/> </xsl:if> </xsl:copy> </xsl:template> <!-- WARNING: this is dangerous. Handle with care --> <xsl:template match="text()[normalize-space(.)='']"/> </xsl:stylesheet>""" def prettyPrint(tree): xslt_doc = etree.fromstring(prettyXSL) if isinstance(tree, basestring): doc = etree.fromstring(tree) else: doc = tree transform = etree.XSLT(xslt_doc) return etree.tostring(transform(doc)) --dirk

I just remembered that Fredrik has an indentation function for ElementTree: http://effbot.org/zone/element-lib.htm Most of the stuff on that page should work unchanged with lxml.etree. Stefan
