AttValue: " or ' expected attributes construct error

how to ignore that the attribute has no " " ?

Solution

  • You input XML/HTML structure has invalid tags/attributes and should be recovered beforehand:

    xmlstarlet solution:

    xmlstarlet fo -o -R -H -D 123.xml 2>/dev/null | xmlstarlet sel -t -v "count(//tag1)" -n

    The output:

    2

    Details:

    • fo (or format) - Format XML document(s)
    • -o or --omit-decl - omit xml declaration
    • -R or --recover - try to recover what is parsable
    • -D or --dropdtd - remove the DOCTYPE of the input docs
    • -H or --html - input is HTML
    • 2>/dev/null - suppress errors/warnings
