Tips
Format XML document
Using xmllint from package libxml2-utils [1]:
xmllint --format doc.xml
XMLLINT_INDENT=" " xmllint --format doc.xml
XMLLINT_INDENT=$'\t' xmllint --format doc.xml | sponge doc.xml
Using xsltproc and XSLT stylesheet. This requires an intermediate XSLT document:
cat > indent.xslt << __HERE__
<?xml version="1.0" encoding="UTF-8" ?>
<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="xml" encoding="UTF-8" indent="yes" />
<xsl:strip-space elements="*"/>
<xsl:template match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
</xsl:transform>
__HERE__
xsltproc indent.xslt doc.xml
Use both single and double quotes in attributes
From the XML specification [2]:
To allow attribute values to contain both single and double quotes, the apostrophe or
single-quote character (') may be represented as "'", and the double-quote
character (") as """.
<element attr="quote " apostrophe '">Foo</element>
