lxml etree xmlparser remove unwanted namespace
import ioimport lxml.etree as ETcontent='''\<Envelope xmlns="http://www.example.com/zzz/yyy"> <Header> <Version>1</Version> </Header> <Body> some stuff </Body></Envelope>''' dom = ET.parse(io.BytesIO(content))You can find namespace-aware nodes using the xpath method:
body=dom.xpath('//ns:Body',namespaces={'ns':'http://www.example.com/zzz/yyy'})print(body)# [<Element {http://www.example.com/zzz/yyy}Body at 90b2d4c>]If you really want to remove namespaces, you could use an XSL transformation:
# http://wiki.tei-c.org/index.php/Remove-Namespaces.xslxslt='''<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"><xsl:output method="xml" indent="no"/><xsl:template match="/|comment()|processing-instruction()"> <xsl:copy> <xsl:apply-templates/> </xsl:copy></xsl:template><xsl:template match="*"> <xsl:element name="{local-name()}"> <xsl:apply-templates select="@*|node()"/> </xsl:element></xsl:template><xsl:template match="@*"> <xsl:attribute name="{local-name()}"> <xsl:value-of select="."/> </xsl:attribute></xsl:template></xsl:stylesheet>'''xslt_doc=ET.parse(io.BytesIO(xslt))transform=ET.XSLT(xslt_doc)dom=transform(dom)Here we see the namespace has been removed:
print(ET.tostring(dom))# <Envelope># <Header># <Version>1</Version># </Header># <Body># some stuff# </Body># </Envelope>So you can now find the Body node this way:
print(dom.find("Body"))# <Element Body at 8506cd4>
Try using Xpath:
dom.xpath("//*[local-name() = 'Body']")Taken (and simplified) from this page, under "The xpath() method" section
The last solution from https://bitbucket.org/olauzanne/pyquery/issue/17 can help you to avoid namespaces with little effort
apply
xml.replace(' xmlns:', ' xmlnamespace:')to your xml before using pyquery so lxml will ignore namespaces
In your case, try xml.replace(' xmlns="', ' xmlnamespace="'). However, you might need something more complex if the string is expected in the bodies as well.
