$ xmlstarlet --help XMLStarlet Toolkit: Command line utilities for XML Usage: xmlstarlet [<options>] <command> [<cmd-options>] where <command> is one of: ed (or edit) - Edit/Update XML document(s) sel (or select) - Select data or query XML document(s) (XPATH, etc) tr (or transform) - Transform XML document(s) using XSLT val (or validate) - Validate XML document(s) (well-formed/DTD/XSD/RelaxNG) fo (or format) - Format XML document(s) el (or elements) - Display element structure of XML document c14n (or canonic) - XML canonicalization ls (or list) - List directory as XML esc (or escape) - Escape special XML characters unesc (or unescape) - Unescape special XML characters pyx (or xmln) - Convert XML into PYX format (based on ESIS - ISO 8879) p2x (or depyx) - Convert PYX into XML <options> are: -q or --quiet - no error output --doc-namespace - extract namespace bindings from input doc (default) --no-doc-namespace - don't extract namespace bindings from input doc --version - show version --help - show help Wherever file name mentioned in command help it is assumed that URL can be used instead as well. Type: xmlstarlet <command> --help <ENTER> for command help XMLStarlet is a command line toolkit to query/edit/check/transform XML documents (for more information see http://xmlstar.sourceforge.net/)
1-2-1. sel help
$ xmlstarlet sel --help XMLStarlet Toolkit: Select from XML document(s) Usage: xmlstarlet sel <global-options> {<template>} [ <xml-file> ... ] where <global-options> - global options for selecting <xml-file> - input XML document file name/uri (stdin is used if missing) <template> - template for querying XML document with following syntax: <global-options> are: -Q or --quiet - do not write anything to standard output. -C or --comp - display generated XSLT -R or --root - print root element <xsl-select> -T or --text - output is text (default is XML) -I or --indent - indent output -D or --xml-decl - do not omit xml declaration line -B or --noblanks - remove insignificant spaces from XML tree -E or --encode <encoding> - output in the given encoding (utf-8, unicode...) -N <name>=<value> - predefine namespaces (name without 'xmlns:') ex: xsql=urn:oracle-xsql Multiple -N options are allowed. --net - allow fetch DTDs or entities over network --help - display help Syntax for templates: -t|--template <options> where <options> -c or --copy-of <xpath> - print copy of XPATH expression -v or --value-of <xpath> - print value of XPATH expression -o or --output <string> - output string literal -n or --nl - print new line -f or --inp-name - print input file name (or URL) -m or --match <xpath> - match XPATH expression --var <name> <value> --break or --var <name>=<value> - declare a variable (referenced by $name) -i or --if <test-xpath> - check condition <xsl:if test="test-xpath"> --elif <test-xpath> - check condition if previous conditions failed --else - check if previous conditions failed -e or --elem <name> - print out element <xsl:element name="name"> -a or --attr <name> - add attribute <xsl:attribute name="name"> -b or --break - break nesting -s or --sort op xpath - sort in order (used after -m) where op is X:Y:Z, X is A - for order="ascending" X is D - for order="descending" Y is N - for data-type="numeric" Y is T - for data-type="text" Z is U - for case-order="upper-first" Z is L - for case-order="lower-first" There can be multiple --match, --copy-of, --value-of, etc options in a single template. The effect of applying command line templates can be illustrated with the following XSLT analogue xmlstarlet sel -t -c "xpath0" -m "xpath1" -m "xpath2" -v "xpath3" \ -t -m "xpath4" -c "xpath5" is equivalent to applying the following XSLT <?xml version="1.0"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:template match="/"> <xsl:call-template name="t1"/> <xsl:call-template name="t2"/> </xsl:template> <xsl:template name="t1"> <xsl:copy-of select="xpath0"/> <xsl:for-each select="xpath1"> <xsl:for-each select="xpath2"> <xsl:value-of select="xpath3"/> </xsl:for-each> </xsl:for-each> </xsl:template> <xsl:template name="t2"> <xsl:for-each select="xpath4"> <xsl:copy-of select="xpath5"/> </xsl:for-each> </xsl:template> </xsl:stylesheet> XMLStarlet is a command line toolkit to query/edit/check/transform XML documents (for more information see http://xmlstar.sourceforge.net/) Current implementation uses libxslt from GNOME codebase as XSLT processor (see http://xmlsoft.org/ for more details)
1-2-2. ed help
$ xmlstarlet ed --help XMLStarlet Toolkit: Edit XML document(s) Usage: xmlstarlet ed <global-options> {<action>} [ <xml-file-or-uri> ... ] where <global-options> - global options for editing <xml-file-or-uri> - input XML document file name/uri (stdin otherwise) <global-options> are: -P, or -S - preserve whitespace nodes. (or --pf, --ps) Note that space between attributes is not preserved -O (or --omit-decl) - omit XML declaration (<?xml ...?>) -L (or --inplace) - edit file inplace -N <name>=<value> - predefine namespaces (name without 'xmlns:') ex: xsql=urn:oracle-xsql Multiple -N options are allowed. -N options must be last global options. --net - allow network access --help or -h - display help where <action> -d or --delete <xpath> --var <name> <xpath> -i or --insert <xpath> -t (--type) elem|text|attr -n <name> [-v (--value) <value>] -a or --append <xpath> -t (--type) elem|text|attr -n <name> [-v (--value) <value>] -s or --subnode <xpath> -t (--type) elem|text|attr -n <name> [-v (--value) <value>] -m or --move <xpath1> <xpath2> -r or --rename <xpath1> -v <new-name> -u or --update <xpath> -v (--value) <value> -x (--expr) <xpath> XMLStarlet is a command line toolkit to query/edit/check/transform XML documents (for more information see http://xmlstar.sourceforge.net/)
2. 検索
$ cat "${HOME}/.config/openbox/lxde-pi-rc.xml" | xmlstarlet sel -t -m 'keybind'
keybind要素を検索したかったが何も表示されず。使い方がよくわからないので諦める。
以下にスクリプトがあるがコマンドで表示できずスクリプトを書かなければ使えなさそう。なにそれひどい。いらね。
